Thermostatic bath taps

How does a thermostatic bathtub faucet work?

The heart of the device is the thermostatic valve with a cartridge, which reacts to the temperature of the incoming water. Inside, there is a special wax element or a bimetallic spring that expands or contracts according to the temperature. This mechanically regulates the ratio of hot and cold water so that the outlet delivers exactly the temperature you have set on the handle.

The whole process takes a fraction of a second. If there is a complete failure of cold water, the thermostat will immediately stop the flow, protecting you from scalding. This is why thermostatic faucets are considered one of the safest elements.

Why choose a thermostatic bathtub faucet?

Imagine you are filling your hot bathtub, and someone in the kitchen turns on cold water in the sink. With a regular bathtub faucet, you would face an unpleasant temperature shock. With a thermostatic bathtub faucet, this will never happen. This smart faucet instantly adjusts to fluctuations in water pressure and temperature in the pipes.

Thermostatic bathtub faucets differ from regular models in that you do not mix the water manually with a lever "by eye," but you set the exact degrees. Additionally, they feature a safety lock to prevent scalding. Thermostatic bathtub faucets are ideal for families with children, seniors, and those who love long, relaxing baths and don’t want to waste time constantly adjusting the right temperature.

How is a thermostatic bathtub faucet better than a regular one?

Compared to a regular faucet, a thermostatic bathtub faucet offers several key advantages:

• constant water temperature – no unpleasant fluctuations
• higher safety – ideal for children and seniors
• water and energy savings – quicker achievement of the desired temperature
• comfort – set it once and forget about it

What to consider before buying a thermostatic bathtub faucet?

Choosing a new faucet is not just about appearance. For a thermostatic faucet to function properly, you need to check the technical setup of your bathroom.

Before purchasing, ask yourself these questions:

• Where is the hot water supply? This is crucial. Normally, hot water is connected on the left. If your bathroom is reversed, a regular thermostatic bathtub faucet will not work. However, there are special models for reversed inputs.
• What is the spacing? If you are replacing an old wall-mounted faucet with a new one, measure the distance between the centers of both water outlets in the wall. Most commonly, you'll encounter 150 mm, but in older apartments, 110 mm is still common.
• Will you use the faucet for showering? Most models have a switch for the shower, but there are also variants designed purely for filling the bathtub.
• What design do you want? Does your bathroom need a luxurious look or rather minimalism?

How to choose a thermostatic bathtub faucet based on installation type

The installation method significantly affects the visual impression of the entire bathroom. At SANITINO, you can choose from several categories:

• Classic wall mount – the most popular option, where the entire body of the faucet is visible on the wall. Installation is quick and easy, ideal for fast renovations.
• Concealed installation – for a minimalist look, choose a concealed solution. Only the control part and the spout are visible. The mounting body is hidden in the wall.
• Edge-mounted faucet – a very elegant solution where the faucet is installed directly into the openings on the edge of the bathtub or into the cladding. It is often combined with a hidden pull-out shower.
• Floor-mounted faucet – a luxurious addition for freestanding bathtubs in the middle of the room. It looks majestic and turns your bathroom into a spa-like space.

Thermostatic bathtub faucet controls

The classic is tap control (one tap adjusts the temperature, the other adjusts the flow). You may also encounter lever control. However, button control is becoming increasingly popular, where you start the water flow with a simple press of a button, which is incredibly convenient, especially when your hands are covered in soap.

Thermostatic bathtub faucet and accessories

On our e-shop, you will find thermostatic bathtub faucets without a shower as well as complete sets with a shower. These sets include a hose and a handheld showerhead, so you can also shower in the bathtub or comfortably wash your hair.

Tip SANITINO: A thermostatic bathtub faucet with a shower is also great for showering pets or children.

Design and colors

Chrome is no longer the only option. A thermostatic bathtub faucet can also be a design unique.

• Black and graphite – ideal for industrial and modern interiors.
• Gold and bronze – add a touch of luxury or retro style to your bathroom.
• White – looks clean and minimalist.
• Stainless steel and brushed nickel – practical surfaces that hide dried water drops better.

Note: For dark surfaces (black, black chrome), pay attention to the quality of the finish. Renowned brands use PVD technology, which is scratch-resistant and chemical-resistant.

Modern technologies and finishes

Global manufacturers are constantly developing technologies that will make your life easier and save you money.

• CoolTouch – special technology that ensures the body of the faucet will never be hotter than the water inside. The surface of the faucet remains cool to the touch, so there is no risk of burning yourself on hot metal.
• EcoSmart – reduces water consumption by up to 60% without sacrificing comfort. The water flow is aerated, making it feel full and soft.
• EasyClean – special surface that prevents the buildup of limescale.
• Burn protection – most models also feature a burn protection mechanism, which is especially useful in families with children.

Tip SANITINO: If you're purchasing a faucet for the bathtub, you may also want to consider thermostatic shower faucets to keep your bathroom in the same style and technological standard. For sinks, thermostatic sink faucets are a great option.

Where to place a bathtub faucet and how to install it?

The correct placement of the faucet determines how comfortable your bathtub filling will be and whether it will cause discomfort while you relax. It is typically installed in the middle of the longer side of the bathtub or near the feet.

We recommend: If you're unsure about your skills, leave the installation to a professional. With thermostatic faucets, accuracy is key for proper temperature calibration.

A thermostatic bath tap mixes hot and cold water just like standard taps. However, it mixes it much faster and then maintains the temperature you set. This is thanks to a valve that reacts immediately to changes in the water supply pressure. Everything happens instantly – fractions of a second make the difference. For example, if someone in the household switches on the washing machine, which temporarily draws hot water, a thermostatic bath tap ensures that the water temperature in the bath does not change. This eliminates unpleasant temperature fluctuations and the risk of scalding. It is an ideal solution not only for households with small children! 

In our range, in addition to thermostatic bath taps, you will also find thermostatic basin taps, thermostatic shower taps, and central thermostatic taps. You can choose from many types – wall-mounted, concealed, or deck-mounted on the bath rim. The highest-quality thermostatic bath taps on the market are manufactured by leading renowned brands such as Grohe, Kludi, Hansa, or Ideal Standard. They will serve you for many years.

Benefits of a thermostatic bath tap

The main advantage of thermostatic bath taps is safety. Most modern models are equipped with a safety feature that prevents the water temperature from exceeding a certain limit (usually 38 °C). This is particularly important for households with small children or elderly people, who are more sensitive to temperature changes.

Another advantage is comfort – once set, the temperature remains stable throughout the entire bath. So when you prepare your favourite bath, you do not need to keep adjusting the water temperature manually and can focus entirely on relaxing.

How to choose a thermostatic bath tap?

When choosing a thermostatic bath tap, it is worth considering several factors. Focus on material quality and useful features. 

Installation of thermostatic bath taps

Just like with standard bath taps, thermostatic models are available in several installation types. In our range, you will find thermostatic bath taps for exposed or concealed installation, as well as more attractive options – floor-mounted or mounted on the bath rim.

Controls of thermostatic bath taps

You do not need to limit yourself when choosing the controls either. Of course, there are lever thermostatic bath taps, but also options with knob or push-button control.

Quality and brand of thermostatic bath tap

The highest-quality thermostatic bath taps on the market are made by leading renowned brands such as Grohe, Hansgrohe, Kludi, Hansa, or Ideal Standard. Popular thermostatic bath taps also include brands such as kielle, JIKA, RAVAK, or Mereo. And if you are looking for designer models, choose from our wide range of bath thermostats by KEUCO, AXOR, Steinberg, or Paffoni. They will serve you for many years.

Design

You do not have to compromise on design either. Just like with standard taps, thermostatic models are available in several styles, sizes, and colours. So you can match your bathroom down to the very last detail!

Technology

Thermostatic bath taps also feature unique finishes and technologies for easier maintenance, lower water consumption, or, for example, anti-scald protection. These technologies vary from one manufacturer to another, but we recommend taking them into account when making your choice. Especially if you want to extend the service life of your thermostatic tap while keeping maintenance to a minimum.
