How To Renovate A Bathroom Guide

Does any of this sound familiar… early morning queues, a shower curtain with a pastiche of mould, tiles that would look more at home in a 2* Eastern European hotel from 1974?

Given how frequently we use it (and the intimate relationship we have with it), it’s surprising that we are often reluctant to undertake works to our bathrooms. Kitchens? Sure … I can’t get enough of a Plain English catalogue (see the Homyze ‘How To’ Guide on kitchens here). Bedrooms? Definitely. We will happily spend hours over ‘just the right shade of white’ for the cornice … only to be oblivious to our surroundings for the majority of the time we spend there (assuming you didn’t opt for red walls). But the poor humble bathroom… 

So, let’s change all that, with our helpful Homyze guide on how to tackle a bathroom renovation. Here you’ll find useful tips and advice to consider when you do decide to breathe new life into your bathroom.

What is the cost of a bathroom renovation?

The first and most important question to ask before starting any renovation project is of course, what’s the cost going to be?

On average, the cost of renovating a bathroom in the UK comes in at around £3,000 but this can vary depending on materials, space and what you’re actually looking to change. Assuming the sanitary ware (bath, toilets, sinks etc.) is staying in the same position, this should be enough to get a ‘new’ bathroom. 

How long will my bathroom renovation take?

The average timeframe for a bathroom renovation is 3-5 weeks, but much like the cost, this can vary considerably (and this estimate doesn’t consider the variety of hold-ups, changes or delays that may arise and which good planning or a helpful Homyze Pro can help to avoid!). 

When planning, always try to work out an achievable time frame in which to complete your renovation. Consider everything from the initial design, the time it takes to source the items you need, any help from a professional tradesperson, as well as the possibility of any unforeseen events. Varying your programme (or not having one to begin with!) can quickly lead to a loss of cost control and even your interest in the project.


Whether it’s a cramped bathroom under the stairs, or an en-suite to rival the size of your master bedroom, knowing what space you have to work with is key to getting the right layout. Take into consideration who will be using the room … non-slip surfaces and a medicine cabinet are higher priorities for a young family over a large luxury bath if forced to decide. 


When it comes down to starting on the renovation, clearing the area of all unwanted fixtures is a great place to start. Make sure to note where all pipes and other water sources are, as the unexpected cost of being ankle deep in water is not a great way to start your bathroom redecorating project.

Design and Decor

Some different bathroom stylesIf you’ve decided to repaint your bathroom, it’s always best to use a specialist emulsion that is both mould and mildew resistant, and always remember to remove any mould beforehand. Consider what colours you want for your bathroom, light colours help create the impression of space, while darker colours offer a warmer, more intimate setting. See our guide on How to Choose Interior Paint for more information.

If tiling, carefully plan on how much area you’ll be covering and the amount of tiles required (plus roughly 10% extra for any breakages). Make sure wall surfaces are sound and prepared for the tiles and adhesive. It’s key to always use a sanitary adhesive, as when working in a wet environment increases the chances of issues such as cracking and mould. 


Discovering your shiny new bathroom has mould can quickly undo all the hard work you’ve put in. The best way to ensure you don’t have to tackle any unwanted mould or mildew problems is through creating a number of options for removing moisture build-ups. A fan that vents outside the room is a great way of resolving the issue, while a fully functioning window can also do a solid job.

Hardware and fixtures

Updating your existing fixtures such as doorknobs, mirrors and toilet roll holders is a great way of changing-up the style of a room but without the hard work and cost. 


When it comes to deciding on a new sink you’ll find there’s a wealth of choice. The most popular types are countertops – designed with the basin on a worktop and storage below. Alternatively, there’s the pedestal, often chosen for its vintage look and its ability to work well in tight spaces, having a single sink atop a slender base. While the more commercial wall-mount offers similar space saving qualities with only the protruding sink and pipes exposed.

Once you’ve chosen the perfect sink for your new bathroom, it’s worth remembering to choose a faucet that fits your room’s style and lets the water run without any obstruction.

The place to sit and ponder all life’s questions, the toilet is a much-cherished spot in every home. Before installing your new toilet, it’s always best to measure the old one while it’s still in place. Calculate the distance between the wall behind and either the bolts that hold the toilet in place or the centre of the drainpipe. It’s worth considering how the new toilet will stand in relation to other new features. It can hardly be considered a throne if your knees are pressed up against the shower. And remember, if you want a wall-hung toilet, this may require special reinforcement (it’s not a great outcome if you skip this step!). If you’re ever in need of some professional plumbing, our Pros are here for you!

Bath and Shower

Example of shower beside bath - how to renovate a bathroom guideThe idea of relaxing in a hot bathtub after a long and stressful day is most people’s idea of bliss, but how often do you really use it. If your answer is rarely, maybe you should ask yourself whether you actually need one. A bathtub can often take up valuable space, and by inserting a shower instead, you can free up both money and room.

If you do decide to forgo the bath and stick with a shower, it’s always worth considering the showerhead.  A handheld showerhead provides you with flexibility, while a fixed showerhead offers a more robust option. The water used during your daily shower quickly adds up, so it’s always worth considering a showerhead that’s flow efficient to help in cutting down those rising household bills.

Tackling a bathroom renovation can be a daunting task, and sometimes hiring a professional to help is worth the extra cost.

In summary

There is a lot to get excited about when doing a new bathroom – but like with many home renovations, it pays to approach it in a methodical manner (particularly if you only have one bathroom in your home as it will be out of commission for a period!).
