The Ultimate Guide to Bathroom Heating

Who doesn’t love a toasty warm bathroom?

In the colder winter months especially, there’s fewer things more satisfying than stepping out of the shower or bath to be greeted by the comforting wrap of a soft warm towel.

But what means should you adopt to heat your bathroom space?

Of course, on an ever-evolving home heating landscape, there’s now more bathroom heating choices than ever before.

In this blog, we’ll take a deep dive into all available bathroom heating options, from radiators to heated towel rails, electric underfloor heating and everything in between.

You’ll be well versed in the pros and cons of every bathroom heating device on the market by the time we’re done, so you can make an informed decision on the best way to heat your bathroom.

The importance of Bathroom Heating

In the way it is used and the heating requirements it possesses, the bathroom really is unique in comparison with any other rooms in the home.

Obviously, a relatively high level of heat and humidity travel throughout the room on account of the bath or shower system. However, whilst areas like the kitchen might also feature high humidity levels, the bathroom will typically be a lot smaller and damper.

All in all, these circumstances combine to create a specific set of heating requirements for the bathroom. So an entirely different bathroom heater could be needed for the bathroom, to be powered via the mains electricity supply or the home’s central heating system.

It’s imperative that you don’t allow your bathroom to become too cold, because those conditions in a humid environment are to dampness what a summer day in Barbados are to us – paradise.

Dampness can be the catalyst for a build-up of bathroom mould, with tiling and wall spaces especially susceptible, particularly so if the space isn’t properly heated or ventilated.

Therefore, it’s vitally important to make the right choice regarding your bathroom heater, selecting a device that delivers an efficient performance and an excellent level of heat retention.

The component needs to suit your space and fall in line with your budget of course, but by taking the above factors into account, you can tackle a potential bathroom mould issue before it even surfaces.

Will the size of the space affect my Bathroom Heating options?

Indeed it will. The size of a bathroom is of the utmost importance when you come to select your bathroom heating.

You’ll have to pay especially close attention to the layout of the space, and consider how your heating choice will fit nearby common bathroom fixtures and fittings.

Think about the way that mirrors, sinks and doors will be affected by the presence of your chosen heating device, in addition to the shower enclosure and/or bathtub.

Mainly though, the heat output has to be the primary attribute taken into account when upgrading your bathroom heating.

You have to be confident that whichever radiator, towel rail or any other heating component you choose offers an adequate level of warmth to heat the bathroom to a comfortable temperature.

A BTU Calculator can be used to assess whether the device you have your eye on will provide a strong enough dispensation of heat to cover the entire bathroom.

The chart below will help you ascertain how much heat is required.

And to further aid your search, the bathroom can be divided into separate zones based on the risk factor posed by an electrical supply coming into contact with water.

This is a major safety concern, so be sure to split the bathroom into four specific zones, then you can decide what sort of equipment or devices, if any, can be installed in each section.

Zone A

The part of the bathroom within a bath or shower enclosure that directly holds water. Essentially, the shower tray or bathtub itself.

Zone B

The area positioned immediately above Zone A – the shower enclosure or bathtub – up to and including a 2.25m distance above the foot of the bath or shower. Zone B does not include Zone A.

Zone C

Incorporates the same height as Zone B – 2.25m – which is extended to 0.6m both horizontally and vertically around the shower or bath.

Zone D

The area of the bathroom where it is unlikely that any water will be used.

What are the different available Bathroom Heating options?

There are three main types of bathroom heating options to introduce – you should think about the specific area of the bathroom you want to heat before coming to a decision.

If freezing cold bathroom tiles are the bane of your life in the colder winter months, for example, you should opt for a style of heating that represents a solution to this problem.

The three standout styles of bathroom heating solutions come in the form of heated towel rails, radiators and underfloor heating…

Heated Towel Rails

Heated towel rails represent a stylish and effective means to heat a bathroom, and are especially popular in compact bathroom areas.

Perfect for keeping towels toasty warm and dry as their moniker would suggest, these devices are ideal if the satisfyingly snug comfort of a warm towel is important to you as you exit the bath or shower.

As alluded to, the only drawback could be that a towel rail wouldn’t provide the necessary level of heat to properly warm up a larger family bathroom. But this can be checked via a BTU Calculator prior to purchase.

Radiators

Radiators are typically the most expensive of the available bathroom heating options. That said, the stylish aesthetic and supreme performance quality typically makes them worthy of the extra outlay.

Usually featuring a wall-mounted profile, designer radiators can add a touch of modern class to the bathroom area. Essentially, they’ll distribute heat evenly throughout the space to ensure a comfortably warm space.

Underfloor Heating

An option that might be dismissed at first glance as an overly expensive, unattainable luxury.

In actual fact though, electric underfloor heating can now be introduced to the home, and more specifically the bathroom, in a variety of cost-effective ways.

The major benefit of underfloor heating is its propensity to warm up your flooring to the preferred temperature, providing lovely underfoot conditions in colder climes.

By contrast, a major drawback is that the entire floor would need to be stripped for the installation of underfloor heating to occur. Therefore, it’s an excellent option to consider when committing to a full bathroom renovation.

Should I choose Manual or Thermostatic Heating?

Manual Heating

The simplest form of home heating control. A heater with a manual valve operates in the same manner as a standard water tap. You control the bathroom temperature by switching the valve on and off.

One of the biggest disadvantages associated with manual heating is that you will need to keep a close check on the bathroom temperature yourself, making sure it’s neither too hot nor too cold.

The best environment to opt for manual heating is a bathroom that perhaps isn’t used all too regularly. Or a space in which the temperature doesn’t drop significantly during the colder winter months.

Thermostatic Heating

With heaters incorporating a thermostatic radiator valve, or TRV, these boast an in-built sensor to keep the bathroom temperature to a consistent set degree.

Thermostatic heating is an ideal selection for the main bathroom in a family household. And for bathroom areas susceptible to big temperature shifts throughout the winter season.

How much will my Bathroom Heating cost to install?

Prices will vary significantly depending on which type of bathroom heating you choose to install.

As you would probably expect though, underfloor heating would tend to be the type to cause the biggest strain on a bathroom heating budget.

The installation process is a lot more involved than with radiators or towel rails, and requires disruption to far more elements, fixtures and fittings. Indeed, it calls for the entire bathroom flooring to be ripped up and re-laid.

Fluctuation in underfloor heating installation prices can occur based on a number of variables.

These include the type of underfloor heating system, the type of floor cover, and the current state of the bathroom. I.e. whether the fitting is for a new bathroom, or a part of some extensive renovation work.

Usually, heating engineers or plumbers will charge between £200 and £300 a day for underfloor heating installation work, dependent on the projected length of the task at hand.

In addition to this, the cost of materials should also be factored in.

For any of heated towel rails, electric towel rails, towel warmers or designer radiators, the cost of fitting is absolutely minimal. Typically, it’s a straightforward job to fit these devices and can usually be completed by anyone with a hint of DIY nous.

What will the running costs of my Bathroom Heating be?

It is admittedly difficult to offer an accurate prediction of bathroom heating costs, as so many different factors need to be taken into account.

For example, affecting variables include the outdoor weather conditions, thermostat settings, how long the heating will be switched on for each day, and the local electricity tariff should you opt for an electric heating solution.

We’ll get onto electric heating options in more detail later, but they are widely renowned for the levels of energy efficiency they provide.

So it might just be that these technologically advanced devices can prove a viable, budget-friendly means to heat your bathroom over time.

How much space do I need to accommodate my Bathroom Heating solutions?

Take it as read that we’re not referring to the all-encompassing underfloor heating option in this section.

But if you are planning to populate your bathroom with a designer radiator or a heated towel rail, the layout of your space, its dimensions and the wall size will influence which types of device are suitable.

As an example, compact bathroom areas with narrow walls won’t prove the best habitat for wide horizontal radiator models.

Thin wall spaces are much more likely to benefit from the addition of a heated towel rail or smaller vertical radiator design instead.

You are open to a wider world of heating choices with a larger bathroom surface area. Essentially, bigger bathrooms will usually mean more wall space, so you can practically take your pick from an immense variety of designer radiators and towel warmers in any shape or size.

Selecting the right Bathroom Heating option for my space

There’s all sorts of different factors that will influence what constitutes the right bathroom heating solution for your space.

Below, we’ve listed some of the more favourable designs for small, medium-sized and large bathrooms with both modern and traditional themes.

You might even find a component fit to become the centrepiece of your bathroom – offering excellence both visually and performance-wise.
