Bathroom renovation can bring a brand new feel and look to your home, increase your property value, and improve functionality which is very important. Who wouldn’t want to do that? But let’s be honest — it’s not as simple as picking a new tile and calling a plumber. If you want to avoid crucial mistakes we have seen happen and even delays, here are 10 essential tips to know before starting your bathroom renovation.
Set a Realistic Budget (and Add a Buffer)
Before you touch anything, figure out how much you’re willing to spend. This is very important. A basic bathroom in the UK can start around £3,000–£5,000, while full renovations with luxury fittings can push £10,000 or more. You should always add 10–15% on top for unexpected issues — like water damage or hidden plumbing problems — that could blow your budget wide open.
Define Your Needs, Not Just Your Wants
Are you updating for resale, growing your family, or just tired of an old bathroom? Focus on function over fashion to begin with. For example, a family bathroom needs storage and durability. A guest en-suite might focus more on style. Be honest about how the space is used before you get carried away on Pinterest.
Choose a Layout That Makes Sense
Changing layouts adds cost and complexity — especially when more plumbing is involved. If the current layout works, keep it. If it works, don’t fix it. If you do want to change it up, check with a local expert to get their honest expert opinion. Simple layout changes (like swapping a walk-in shower for a new bath) can make a big difference without tearing everything apart; it’s not always needed to do.
Don’t Cheap Out on Waterproofing
You’d be shocked how many bathroom “renovations” fail because someone skimped on waterproofing. Wet areas like showers and floors must be taken care of properly to prevent leaks and mold. It’s important to put your money in the right systems and get them installed by a professional who understands the UK building regulations.
Focus on Ventilation
Bathrooms are naturally humid. They have poor ventilation as a breeding ground for mold. Make sure you have an extractor fan installed that meets building regulations; otherwise your new bathroom won’t be very new for long. Window vents alone won’t cut it, especially in colder times like the winter.
Prioritise Lighting From the Start
Lighting in a bathroom can make a big difference whether it’s LEDs under your cabinets or ceiling lights for general use or maybe even wall lights. Whatever lights it is that you’re thinking about, make sure they are IP-rated and safe for wet zones. This isn’t something you want to DIY unless you’re a professional.
Measure Twice, Buy Once
It’s important to check your dimensions twice no matter what it is. You would be surprised how many people buy things too big or too small because of wrong measurements. You also want to make sure you can get everything through the bathroom door; otherwise there won’t be a bathroom install.
Think About Storage Early On
Clutter ruins a bathroom’s look fast. Don’t wait until the end to panic about where you’ll put your towels or toiletries. It’s always best to plan in advance. Wall-hung vanity units, shelves in the shower, and mirrored cabinets can all add functional storage without eating into space.
Hire the Right Professionals
There’s no shortage of “bathroom fitters” out there, so it’s crucial to find someone with experience, the correct qualifications, and excellent customer service to make all the difference. Look for professionals with strong reviews on Google or Facebook, clear communication so you can discuss your thoughts with them, and who are happy to walk you through the process.

Don’t Forget the Details

Don’t forget the small touches that bring everything together — for example heated towel rails, toilet flush plates, and most important: where is the toothbrush going? We recommend making a checklist and going through everything to make sure you’re not missing out on functionality.
