Shower Types Explained

Post by WM Wetroom Materials

Naturally, one of the standout features in a wetroom is the shower, and in some cases, this is the central focal point of the room. When deciding on the shower type to integrate into a wet room, there is a range of factors to consider, from functionality to aesthetics and the space available. Below, we’ve explained the different shower types that are out there, and the different benefits and which wet room each would be best suited to.

Power Showers

A power shower draws water from both hot and cold water supplies, with the temperature of the water generally being thermostatically controlled. One of the key benefits to users of powers showers is that unlike other shower types available, they offer low-pressure systems the option of a glorious high flow rate shower. In order to fulfil this functionality, power showers generally have a pump inside a box on the wall (this helps to boost the water flow and pressure), and this is what allows a stronger, thermostatically controlled shower, for optimum temperature and pressure. It’s worth mentioning, that having a power shower means a greater volume of water is being used, and therefore a larger drainage system is required to manage this.

However, it is worth noting that this type of shower generally comes with an added element of expense. Both running and maintenance costs can be high; running a power shower can cost users twice as much per year vs an electric shower, so this should be made aware. Furthermore, in order to ensure the correct level of performance from the shower, the pump could require maintenance which again occurs further cost.

Electric Showers

An electric shower is common-place in bathrooms and wetrooms, and it’s easy to see why with ease of installation, energy efficiency and the range of different styles and finishes that are available. Electric showers work by drawing on the cold water supply, and then as the water passes through the electric shower is it heated to the required temperate. Unlike some power showers, electric showers are generally simple to fit and don’t usually require any additional plumbing work to be done to a bathroom or wetroom.

One of the key benefits to the user of an electric shower is how energy efficient they are. Some are reported to be 99.7% energy efficient, with no hot water wastage being occurred; amazing for those who are looking for an eco option in their wet room. Because of this, it means we’re not only doing our bit for the planet but also for our wallets! Electric showers can also easily fit a range of wetroom styles; coming in a variety of finishes from white to chrome.

Whilst flow rates are generally lower, there is the option to choose a higher kilowatt rating for better flow performance if you so desire without having to switch to a different shower type.

Digital Showers

Digital showers embrace everything a user could want in a shower; state of the art technology, stylish choices and ease of installation. Both the temperature and flow of the shower is controlled by a panel that communicates with the shower’s power unit. In many cases, the power unit is installed in either an airing cupboard or loft.

The control unit that is used to change the temperate and flow of their shower can either be located in a user’s shower or elsewhere within the bathroom if they so please. This then communicates with the shower via a cable or wireless technology. Digital showers are available in either mixer or electric variations, so there are plenty of choices out there!

The water inside the shower, much like the electric shower, is controlled by a thermostat which mixes hold and cold water to get the perfect temperature. This means no nasty changes in water temperature when other appliances in the home are being used!

This high-tech shower option can come with both touchscreen and colour coded displays, creating a perfect futuristic user experience. One of the best thing about a digital shower? You can turn the shower on without actually getting in, so need to experience that uncomfortable cold blast of water before it gets up to temperature.

Mixer Showers

Mixer showers are generally dependant on a hot water system, so it’s important to make sure the style and model are compatible with a users’ system. Alike other shower types, mixer showers use both hot and cold water supplies and can deliver higher flow rates than some electric showers. This makes mixer showers ideal for homes that have a combi boiler, or large capacity hot water cylinder (where hot water is readily available).

This type of shower is highly versatile, with various options out there to suit any aesthetic. There’s fixed heads, adjustable heads, exposed variables or styles that are built into the wall (BIR). You’ll find a fit for any wetroom.

However, it is worth noting that one of the drawbacks with mixer units is that they are affected by water use in other parts of the house. So if someone flushes the toilet, you might experience a bit of shock from temperature change!

 

Important update to the NHBS Specifications 2018

Backing surfaces for tiling should;

  • Be moisture resistant, where frequent wetting occurs 

When Tiling; 

  • Proprietary water-resistant grouting should be used in accordance with the manufacturer 

Grouting should be: 

  • As specified in the design including mix and colour 
  • Cement-based, epoxy resin or a proprietary product 
  • ‘Waterproof in and around shower enclosures and where tiling can be saturated’. 

Gypsum plaster should not be used where; 

  • ‘Repeated or persistent wetting may occur’
