Basically, a thermostatic shower is one that has thermostatic valves installed. These valves helps to keep the temperature of the water in the shower at an even temperature, even if water is being used in other parts of the house (dishwasher, washing machine, etc.). There is also a diverter valve which controls the flow of water from the bathtub outlet and the shower head.

Thermostatic shower valves are a relatively new type of bathroom valve system that has been on the market for just a few years. They were originally developed and designed for use in spa bathrooms. They work by adjusting to the changing temperature of the water within the shower enclosure.

Many people consider this a very desirable feature because it helps to control the temperature of the water but also helps to avoid scalding or burns when using a hot tub or shower.

There are many different types of shower systems, and they all revolve around saving water, but for simplicity we use the term “shower” to refer to a shower. There are thermostatic shower systems that are equipped with a digital thermostat, which is most likely a manual mixing shower controlled by a temperature controller.

A thermostatic valve is designed to maintain a temperature between 70 and 110 degrees using a dial or a temperature handle. This includes the supply of cold water, which is interrupted only by the use of a pressure equalizer valve, not by digital temperature control.

Are Thermostatic Shower Valves Worth It?

The price of these valves can vary greatly depending on the features offered, but generally they cost between $50 and several hundred dollars. This is an investment that many homeowners may find themselves paying off for many years to come.

You should definitely take the time to check out all the different valves that are available before deciding which one is the best choice for your bathroom. Not only will you want to compare prices but you will want to look at the styles as well. A bathroom with a mixer valve or a rain shower feature can be more expensive than one without those features.

Thermostatic shower valves can be controlled either manually or electronically. Most of the valves will have two different controls. You can choose to either turn on and off the valves by turning their handles, or you can simply “program” the valves to start and shut off based on whether you want hot or cold water in your shower. The valve is used in conjunction with a thermostat to make sure that the valves work correctly.

Why would you want to buy one of these valves?

Well, if you have a leaky pipe in your tub, one of these valves might be able to help you fix the problem before you call a plumber. When you have a leaky pipe, you have to constantly add more hot water to your tank to ensure that all of the water in the tub is heated. If you had a valve that could program to shut off the supply of hot water when the hot water reaches a certain temperature, you would never have to worry about running out of hot water.

What Is The Difference Between Pressure Balance and Thermostatic?

The main difference between pressure balance valves and thermostatic valves are…

A thermostatic valve senses and controls the actual water temperature, while a pressure-balance valve senses and controls only the ratio of hot water to cold. Which works best? As always, it depends on preference and budget. - plumbingsupply.com

Most homeowners have to make a decision on shower valves only when they are remodeling their bathrooms or having one built.

Choosing tiles and shower heads and what type of doors (if any) to put in your shower are just the aesthetics but can give you the luxury feeling that many homeowners look for in their shower experience.

The right shower valve can also add to that as well.  Frankly, choosing the right valve is a very important aspect in the goal of creating that luxury spa shower!
