Vittoria shower valve vs. bathtub valve – what is the difference and which one to choose

When a customer stands in the store or browses an e-shop looking for a bathroom faucet, they most often stop at two product lines: the shower valve and the bathtub valve. At first glance, they look similar – a chrome finish, a lever, an outlet. But when you start comparing technical specifications, mounting dimensions, outlet height, and overall configuration, you will find that these are fundamentally different products that are not interchangeable. From experience, I know that confusing these two types of valves is one of the most common mistakes during bathroom renovations. The result? Unnecessary costs for plumbers, re-digging, a new valve. This article will explain everything you need to know before ordering a valve from the Vittoria range.

Basic differences between shower and bathtub valves

First, let's clarify the terms. A shower valve is designed exclusively for a shower enclosure – its primary function is to regulate the temperature and flow of water that exits through the top outlet to a fixed showerhead or to a handheld shower via a hose. A bathtub valve is primarily used for filling the tub via the lower outlet arm and also allows switching to the shower using a diverter. Each of these types has different mechanical, hydraulic, and aesthetic solutions.

From a construction point of view, they differ mainly in three areas: the height of the mounting body, the presence and type of water direction switch (diverter), and the height of the outlet arm. A shower valve is usually more compact, without a long outlet arm, while a bathtub valve has an outlet arm 15–22 cm long that points over the edge of the tub and may include either an integrated rotating diverter or a lift-and-turn diverter directly on the outlet.

Dimensions, mounting height and spacing of connection holes

One of the most common problems in practice is that a customer buys a valve without knowing the dimensions of the existing connection holes in the wall. Vittoria valves – like most European manufacturers – use a standard spacing of 150 mm between the axes of hot and cold water. This number is mandatory and fixed: if your wall is prepared for 150 mm, both series (shower and bathtub) will fit equally well in terms of spacing.

Where they differ is in the mounting height above the floor and the required height of the outlet arm:

Shower valve: is usually mounted at a height of 90–110 cm above the floor of the shower enclosure. The outlet hole on the body of the valve (for the handheld shower hose) is at a height of approximately 95–115 cm. A fixed ceiling-mounted shower requires a separate top connection, or a shower valve with a top outlet can be used.
Bathtub valve: is mounted at a height of 60–75 cm above the edge of the tub, which, with a standard tub height of 55–60 cm from the floor, corresponds to a mounting height of 115–135 cm from the floor (depending on the tub design). The outlet arm has its own length of 15–22 cm and points over the edge of the tub.

These values are not just recommendations – they are technical limits derived from hydraulics. If you install a bathtub valve too low, the outlet arm will not clear the edge of the tub and water will spray. If the valve is too high, the arm intrudes into the space and looks aesthetically unharmonious. More about dimensions and outlet height can be read in the topic Vittoria valves: dimensions, connection and outlet height – what you need to know before installation.

Diverter – the heart of the bathtub valve

The technical component that distinguishes a bathtub valve from a shower valve is the diverter (deflector, water direction switch). It is a valve that mechanically redirects the water flow from the lower outlet arm (for filling the tub) to the top outlet (for the handheld shower via a hose). There are two basic types of diverter:

Lift-and-turn diverter: located directly on the outlet arm – the customer pushes or pulls a small button up to redirect the water to the hose with the showerhead. After finishing the shower and closing the water, the diverter automatically returns to the "tub" position, which is important to prevent the customer from being unexpectedly sprayed with cold water when opening the water again.
Rotating (side) diverter: located on the side of the valve body, it is operated by rotating a knob or lever. This variant is mechanically more robust and is more common in thermostatic bathtub valves.

A shower valve does not need a diverter in this sense – water always flows in one direction, either to a fixed head (through the wall/ceiling) or to a handheld shower via a hose. If a shower valve has two outlets (for example, for a ceiling and side shower), it contains a simple direction switch, but this is not functionally equivalent to a bathtub diverter.

Thermostatic vs. single-lever construction for shower and bath mixers

Regardless of whether it is a shower or bath mixer, each type is available in two basic control constructions: single-lever (cartridge) and thermostatic. The difference is crucial for everyday use.

Single-lever mixer controls temperature and flow with one lever – turning it sideways changes the temperature, while moving it up/down regulates the flow. It is cheaper, easier to maintain, and sufficient for most households. The cartridge is a standardized component and is easily available for Vittoria mixers. More about the differences between lever types can be found in the topic Single-lever vs. double-lever Vittoria mixer – which one is suitable for your bathroom.

Thermostatic mixer has two separate control elements – one for setting the desired temperature (thermostat, usually with a limiter at 38 °C or 42 °C for children's safety) and another for regulating the flow and possibly switching outlets. A thermostatic mixer remembers the set temperature even after the water is turned off, which is a huge advantage for morning showers: you open the water and within 3–5 seconds you have the exact temperature, without guessing. Thermostatic mixers are recommended for households with unstable hot water pressure – for example, where several people simultaneously use hot water (families with children, larger apartments).

In practice: if you are equipping a bathroom for one or two people with a standard bathroom, the single-lever version is fully sufficient. If you have small children, seniors, or a bathroom with unstable hot water temperature, a thermostatic mixer is an investment that pays off in comfort and safety.

Water flow and pressure – what influences the choice

Another technical parameter that is often overlooked when choosing between a shower and a bath mixer is water flow and required pressure. A shower mixer operates with a lower flow – for a standard handheld shower, 6–10 liters per minute is sufficient. A bath mixer, on the other hand, must ensure sufficiently fast filling of the bath (volume 150–180 liters), which at a standard flow of 15–20 l/min means a filling time of 8–12 minutes.

Vittoria mixers operate standardly at a static pressure of 0.05–1.0 MPa (0.5–10 bar). The minimum operating pressure for reliable function is usually 0.1 MPa (1 bar). A bath mixer at lower pressure may not fill the bath quickly enough, which customers perceive as a product defect – yet it is a problem of the household water supply system. More detailed information about pressure requirements can be found in the topic Water pressure and Vittoria mixers – what minimum pressure do you need for proper function.

When to choose a Vittoria shower valve

A shower valve is the right choice in the following situations:

You have a shower room without a bathtub. This is the clearest case. A shower room, whether with a shower tray or a built-in floor-level shower (walk-in), requires a shower valve. A bathtub valve would not fit here, neither technically nor aesthetically.
You are renovating and replacing a bathtub with a shower room. We still see bathrooms where the customer removes the bathtub and installs a shower room. In this case, you also need to replace the valve – the old bathtub valve (with a spout and diverter) must be replaced with a shower valve. The supply pipes remain at the same height, but you must check whether the height is suitable for a shower valve (90–110 cm).
Small bathroom without space for a bathtub. In city apartments with bathrooms under 4 m², a shower room is practically the only meaningful option. A shower valve is compact and does not take up space with an overhead spout.
You want a fixed ceiling or side shower (rain shower). Multi-zone shower systems (ceiling shower + side jets + handheld shower) require a shower valve with multiple outlets or a thermostatic valve with a diverter for the shower. A bathtub valve has no place here.

When to choose a Vittoria bathtub valve

A bathtub valve is the right choice in these cases:

You have a bathtub and want to also take a shower. A bathtub valve with a diverter is a classic solution: you fill the bathtub with the spout, and when you want to shower, you pull the diverter and use a handheld shower on a hose. Simple, proven, and cost-effective.
Bathroom renovation with a bathtub that remains in place. If you are only replacing the valve but the bathtub stays, it is logical to replace the old bathtub valve with a new bathtub valve. The pipe positions are at the same height, and the connections are the same.
Combination of bathtub and shower area. In some bathrooms, the bathtub is positioned so that it also serves as a shower area – a shower curtain or glass wall is placed above the bathtub. Here, a bathtub valve with a diverter and a handheld shower on a hose is an ideal solution.
Large bathroom with a freestanding bathtub. Luxury freestanding bathtubs usually require a special bathtub valve – either a standing one (floor-mounted) or a wall-mounted one. The Vittoria range covers both approaches.

Compatibility with existing plumbing – what to check before ordering

From experience, I know that most complaints and returns of valves are not related to product quality, but to the fact that the customer did not check the connections before ordering. Here is a checklist I recommend to everyone before purchasing a valve:

Distance between the centers of hot and cold water inlets: Measure the distance between the centers of the hot and cold water inlets. The standard distance is 150 mm. Vittoria valves are designed for this distance. A deviation of ±5 mm is usually compensable with eccentric couplings (adjustable extension inlets).
Thread of the inlets: The standard thread is ½" (G ½). Vittoria valves use this thread. Check whether your inlets are not ¾" – this can happen with older plumbing systems.
Height of the inlets above the floor: For a shower valve, the inlets should be at a height of 90–115 cm. For a bathtub valve, it depends on the height of the bathtub edge, typically 110–135 cm. If the inlets are at the wrong height, you need to modify the plumbing – a new valve will not solve the problem.
Depth of the embedded inlets: Some inlets are embedded deeply, others protrude. The eccentric couplings of Vittoria valves allow compensation up to about 20–25 mm.

If you are unsure, we recommend consulting with a plumber before purchasing. A good plumber can tell you in 20 minutes what you have in the wall and which valve you need. This will save you nerves and money.

Aesthetics and style – how Vittoria valves fit into bathroom design

Functionality is the basis, but the bathroom is also a space where you spend time and where visual impression matters. Vittoria offers valves in several surface finishes and design lines – from classic chrome through brushed nickel to matte black finish, which is very popular in recent years.

When choosing between a shower and a bathtub valve from a design perspective, the rule applies: both types should come from the same range (collection) to match the handle shape, surface finish, and proportions of the valve body. If you have a combination of a shower room and a bathtub in one bathroom (which is common in large bathrooms), be sure to invest in making both pieces from the same line. Visual inconsistency of valves in the bathroom is an aesthetic mistake that customers later regret.

Vittoria valves are designed to fit both modern and classic bathrooms with their shape. Rounded lines are suitable for romantic, more traditional interiors, while more angular shapes suit minimalist, Scandinavian, or industrial bathrooms.

Installation – essential differences between shower and bathtub valves

From an installation point of view, both types are relatively similar – both are screwed into wall flues using eccentric brackets and sealing rings. The difference lies in the installation position and in additional components:

Shower mixer: After fixing the body of the mixer to the wall, connect the hose for the handheld shower (typically 1.5 m, thread G ½) and install a shower rod or fixed shower bracket. It is important to seal the hose – always use the seals provided by the manufacturer, never just Teflon tape without a gasket. The step-by-step installation process is described in the topic Step-by-step installation of the Vittoria basin mixer – a mistake-free procedure, where the principles are also applicable to the shower mixer.

Bathtub mixer: In addition to the body of the mixer, it is necessary to install the outlet arm (if it is not integrated – some models have a detachable one). When installing a bathtub mixer to a freestanding tub, choose a floor stand (standing mixer), which is a completely different procedure from wall mounting. Be careful to ensure that the arm points exactly above the center of the tub – an aesthetic deviation of 2–3 cm is visually noticeable.

Sealing for both types of mixers should be checked after each installation and after the first water start-up. Leaking connections at the eccentric brackets are the most common cause of moisture behind the tub or in the shower area. If you encounter leaks, follow the topic Leaking Vittoria mixer – causes and leak repair.

Service, cartridges and spare parts

One of the advantages of Vittoria mixers is the availability of spare parts – especially cartridges and seals. The cartridge is the heart of a single-lever mixer: it controls temperature and flow. With proper maintenance (regular cleaning of the aerator, protection against limescale), the cartridge lasts 8–15 years. Both the shower and bathtub mixer use the same type of cartridge within one product line, which simplifies service.

The bathtub mixer also has an additional component that the shower mixer does not have – a diverter. Diverter valves are more prone to wear than cartridges, as they are used daily and are exposed to mechanical stress. A common sign of a worn diverter is that it cannot hold the "shower" position and slides back automatically – water flows through the arm instead of the hose. The solution is to replace the diverter, or the entire outlet arm. More about component replacement in the topic Replacing seals and cartridges in Vittoria mixers – when and how to do it.

Both series of mixers require the same routine maintenance: regular cleaning of the surface (soft cloth, without abrasive agents), cleaning the aerator from limescale, and checking the seals at the eccentric brackets once a year. A detailed procedure can be found in the topic Cleaning and maintenance of Vittoria mixers – how to extend lifespan and preserve shine.

Price range and what affects the price

Within the Vittoria range, the prices of shower and bathtub mixers are in a similar range – the difference between equivalent models of both types is usually not dramatic. The following factors have a greater impact on the price:

Type of control: Thermostatic mixers are significantly more expensive than single-lever ones – usually 2–3 times more. The difference is justified by the precision of temperature regulation, longevity, and comfort.
Surface finish: Matte black or gold finishes are more expensive than standard chrome. Expect a 20–40 % premium compared to the chrome version.
Accessories in the package: Some shower mixers are sold as a set with a rod, handheld shower, and hose. This is more cost-effective than buying components separately – check the package contents before purchase.
Certifications and warranties: Vittoria mixers meet European standards for potable water. Warranty conditions and specifications can be found in the topic Frequently asked questions about Vittoria mixers – warranty conditions, spare parts and compatibility.

Practical scenarios from practice

Scenario 1: Reconstruction of a panel apartment bathroom. The customer has an old bathroom with a tub and wants to modernize it, the tub remains. The flues are at a height of 120 cm from the floor, spacing 150 mm, thread G ½. Correct solution: Vittoria bathtub mixer from a modern line, same installation height, replacement in 30 minutes without demolition. Wrong choice would be a shower mixer – it would fit in height, but the outlet arm for filling the tub would be missing.

Scenario 2: New bathroom with a walk-in shower. The customer is building a new house, the bathroom is 8 m² with a built-in shower and no tub. They want a ceiling rain shower and a side handheld shower. Solution: thermostatic shower mixer with two outlets (diverter between the ceiling and side shower), installed at a height of 110 cm. A bathtub mixer would be absolutely unsuitable here.

Scenario 3: Small bathroom, combination of tub and shower. The customer has a 5 m² bathroom with a tub, a shower curtain above the tub. They want a cheap but functional solution. Correct choice: bathtub mixer with a lift diverter and handheld shower on a hose. This is a classic, proven solution for thousands of Slovak apartments – simple, cheap, functional and easy to service.

Scenario 4: Replacement after a failure – the customer ordered the wrong type. The customer ordered a shower mixer, but has a tub. The mixer arrives, the plumber discovers that the outlet arm and diverter are missing. The mixer is returned, the correct bathtub mixer is ordered, delay 3–5 days, unnecessary transportation costs. This can be easily avoided by reading this article before ordering.

Most frequently asked questions (FAQ)

Can I use a shower mixer instead of a bathtub mixer if I have a tub?

It is not recommended and in most cases it is not even practically feasible. A shower mixer does not have an outlet arm for filling the tub and lacks a diverter for switching between the tub and the hose. You could improvise with a hose hanging over the edge of the tub, but the result would be aesthetically and functionally unsatisfactory. The correct solution is always a bathtub mixer for a tub setup.

Can I use a bathtub mixer in a shower area?

Technically it is possible – a bathtub mixer also has an outlet for a handheld shower via a diverter. However, practice shows several problems: the outlet arm is an obstacle in a shower area, the installation height of a bathtub mixer (approx. 120–135 cm) is higher than the recommended height for a shower area, and the overall impression is impractical. For a shower area, always choose a shower mixer.

What is the difference between a shower mixer with an upper outlet and one without it?

A shower mixer with an upper outlet (G ½ thread on the top side of the body) allows connection of a fixed ceiling or under-ceiling shower. Mixers without an upper outlet have only a side outlet for the hose of the handheld shower. If you plan a ceiling shower, check whether the mixer has an upper outlet – a side hose alone is not enough. Always check the complete product description in the category Vittoria mixers before purchase.

How do I recognize a worn diverter and know it needs to be replaced?

A worn diverter is indicated by the fact that after switching to the "shower" position, it does not hold – it slides back automatically and water flows through the arm. Another sign is water leakage through the arm even when the shower is on. The solution is to replace the diverter or the entire outlet arm. It is an inexpensive repair that a skilled DIY enthusiast can handle without a plumber.

Is a thermostatic mixer suitable for both types (shower and bathtub)?

Yes, a thermostatic solution exists for both types. A thermostatic shower mixer is suitable for family homes and households with children, where consistent temperature is important. A thermostatic bathtub mixer is the most comfortable solution for a tub – you set the temperature once and always fill the tub under the same conditions. A thermostat is also a guarantee in the case of unstable hot water pressure.

Must a bathtub mixer always include a handheld shower in the package?

No, it depends on the specific model. Some bathtub mixers are sold as a set (mixer + handheld shower + hose), others only as the mixer itself. Always check the package contents in the product description when purchasing. If the hose and handheld shower are not part of the set, they need to be purchased separately – the recommended hose length is 1.5 m, G ½ thread on both ends. The Vittoria range also covers accessories, so you can assemble a complete set from one collection.

Conclusion – practical summary before purchase

The choice between a shower and a bath faucet from Vittoria is not a matter of taste, but of technical logic. If you have a bathtub – choose a bath faucet. If you have a shower cubicle – choose a shower faucet. If you have both in one bathroom, each space will get its own faucet from the same line. Always measure the spacing, height and type of holes, check the installation height and verify the contents of the package before ordering.

An investment in the correct type of faucet is an investment in comfort for 10–15 years. Vittoria faucets are designed to last exactly that long with regular maintenance – and to look good while doing so.
