Step by Step Bathroom Renovation Guide (and common mistakes to avoid!)

Bathroom Renovations in North London

The bathroom is arguably one of the most rewarding rooms in the house to renovate. Do it right and it’ll bring you years of pleasure. But do it wrong and it might end up being your biggest nightmare.

If you’re planning house renovations, North London homeowners should start with the bathroom: it’s a great way to freshen up the look and feel of your home. But before you start taking tiles off the walls or removing the bathtub, you need to understand exactly what you’re in for.

At Combit Construction, builders in North London, as a team of specialist builders, we’ve completed many successful bathroom remodel projects. And that’s why we’ve put together this step-by-step guide to help you through each stage of your project: we don’t want you to make any of the common DIY mistakes!


This might sound obvious, but we can’t put enough emphasis on planning! The more forethought and effort you put into planning, the more straightforward your project will be.

Draw out the footprint of your bathroom area and plot in each item (e.g., bath, shower, toilet, vanity etc.) to see how you can maximize your space. Remember, you must allow enough room for doors to open and for free movement within the space.

At this stage, it’s important to concentrate on functionality rather than aesthetics.


The bathroom is an important room in your home, so you’ll need a quality builder to manage your project. It’s always wise to get more than one quote and compare them. Arrange a time for your builder to visit your property to make a physical assessment of your renovation project: a face-to-face meeting is a great opportunity for you to assess each builder’s punctuality, professionalism, and overall approach to your project.

Perfect home builders


A budget for your renovation project is essential. Failure to budget may have devastating results: there’s many an unfinished bathroom renovation out there waiting for the cash for completion! Accuracy in budgeting is super important so talk to your builder about the costs involved in each stage of your project.

When you’re undertaking a renovation project, you’re working with an existing space rather than starting from scratch, so it’s always wise to allow an amount in your budget for ‘unexpected’ expenses. Having that flexibility or leeway will help to minimize the risk of serious budget blow-outs.


Tiles, vanity, paint color, fixings… there’s so much to choose! Try to stick to an overall theme that compliments the rest of your home. The bathroom color trends for 2021 are focusing on soft pastels, whites and greys, while the never-fail black and white combination remains an all-time favorite. The choice is yours, so pick a color scheme that you find relaxing and soothing – after all, the bathroom is a place we all have to spend time each day!

Step by Step Bathroom Renovation Guide


If there’s one room in the home that undergoes serious stress, it’s the bathroom: moisture, rapid changes in temperature and constant wear and tear… it all happens here.

When it comes to choosing tiles, vanities and fixtures, choose items that are designed for wet areas. Get the best your money will buy: not only will these items make your bathroom look and feel more luxurious, but they’re more likely to stand up to the constant demands of daily use.

Talk to your builder about any concerns you may have in this area. Ask for advice – you want your project done right, first time round!


We get it: there’s nothing glamorous about a bathroom fan. And in all the excitement of choosing the showy items, it’s easy to overlook this little workhorse of the bathroom! Ensure that your fan is adequate for the size of your bathroom – efficient and effective moisture extraction is essential for preventing mold and mildew buildup down the track. This is especially important if your bathroom doesn’t have an opening window.


Once your builder has completed his part of the renovation, it’s time for you to work your magic! Curtains, decorative shelving and pot plants are the little things that turn a beautiful room into a gorgeous one – let your creative juices flow and enjoy your new space!
