When it comes to home improvements, a bathroom renovation is one of the most transformative and worthwhile investments you can make.
Recent research suggests that a bathroom renovation can increase a property’s market value by up to 5%.
At Cwtch Haus, we have over 15 years of experience in bathroom renovation, and we have witnessed bathroom design evolve significantly in recent years, shifting from traditional bathroom upgrades to thoughtfully designed spaces that focus on comfort and wellbeing.
Today’s bathrooms are no longer purely functional; they are personal retreats designed to support everyday wellbeing.
Whether you are replacing a tired ensuite, transforming your family bathroom, or installing a contemporary wet room, Cwtch Haus can manage your bathroom renovation from design through to completion, creating a beautifully bespoke space which reflects your personal style, lifestyle, and needs.
In this guide, we will look at how to renovate a bathroom, what it costs, how long it takes, and how you can add sustainable options to your bespoke bathroom design.

How to renovate a bathroom
There are many aspects to consider when planning how to renovate a bathroom, but most importantly, a successful renovation requires careful planning and expert installation by professional bathroom installers.
Based on our expertise, here is how you can approach your bathroom renovation step by step.
Assess Your Existing Bathroom
Take a look at your current bathroom and think about what works and what is missing.
Do you need extra storage? Does the existing layout maximise the usable floor space?
Are your current fixtures and fittings outdated in style or coming to the end of their life?
Choose Your BATHROOM Theme
Decide the theme and style you would like for your new bathroom.
Are you looking for luxury, durability, or something eco-friendly?
Many of our recent bathroom renovation projects have embraced spa-inspired interiors with a growing interest in biophilic design, wellness, and natural materials.
Whichever theme or style you go for, remember that your bathroom needs to look after the whole family. If you are a large, busy family, you might opt for a contemporary bathroom with hard-working fixtures and energy-efficient technology such as a smart shower.
Set a Realistic Budget
The cost of your bathroom renovation will largely depend on the size, specification and finish of your bathroom.
If you set a realistic budget at the start of the renovation, you can make better design choices and avoid overspending later on.
Choose Your Bathroom Layout, Fixtures, and Fittings
Choosing the layout of your bathroom is a big decision that can influence the cost and timeline of your bathroom renovation.
If your existing bathroom layout functions well, then there is no need to change it!
However, if your existing bathroom layout is awkward and a bespoke design could provide a better, more efficient use of space, this often requires relocating plumbing, which increases both time and cost.
Work with Professional Bathroom Installers
Your bathroom renovation will require specialist trades such as plumbing, electrical, waterproofing, plastering, tiling, and many more!
Working with a professional bathroom installer ensures a quality finish and a seamless, stress-free installation.
At Cwtch Haus, we have over 15 years’ experience installing bespoke bathrooms for homes across West Wales.
We have our own in-house bathroom design team and only work with trusted partners.
All of our fixtures and fittings come with manufacturers' warranties, and we offer a comprehensive aftercare service for your peace of mind.

how much does a bathroom renovation cost?
As every Cwtch Haus bathroom is designed and built bespoke, the overall cost will depend on the size of your bathroom space, your chosen specification, and the level of finish.
Costs are mainly influenced by elements such as:
The size and layout of your bathroom.
Plumbing and electrical works.
Fixtures, fittings, and tiling.
Bespoke bathroom cabinetry.
Structural work and waterproofing.
At Cwtch Haus, we offer a free home measure and design consultation so you can explore the possibilities for your bespoke bathroom with no cost or obligation.

On average, a full bathroom renovation takes between 3 and 5 weeks. bespoke bathroom, Camille,
If significant plumbing or structural works are required, your renovation might take between 5 and 7 weeks, possibly longer, but we will provide clear timelines for installation during the design process.
Timelines will depend on the size and complexity of your bathroom space, material lead times, any structural works required, and bespoke fittings.
We have our own installation team who will manage every stage of your bathroom installation from start to finish, so you can be sure of a stress-free installation and the same high standards from design through to completion.
planning a bathroom renovation
Planning a bathroom renovation is exciting, but it can feel overwhelming when you consider all of the elements involved.
There will be materials, fixtures, and fittings to be ordered, tradespeople to be coordinated, and sometimes structural works.
One of the best reasons to choose Cwtch Haus for your bathroom renovation is the ease of our installation process, which is carried out by our in-house installation team and trusted partners.
As the first step in planning your renovation, we offer a free no-obligation home measure & design consultation, and we would also recommend you visit our bathroom showroom in Haverford West, Pembrokeshire.
In the early stages of planning your new bathroom, we will create 3D visuals of your bespoke bathroom design, along with material boards for you to see and touch.
When planning your bathroom renovation, some of the things we will consider include:
Layout and storage.
Lighting and ventilation.
Materials and finishes.
Future-proofing.
When works commence, there might be times when your water supply is switched off to enable the installation of plumbing fixtures, but these are things that we will schedule well in advance, at times most convenient for you.
We will do everything we can to minimise disruption to your household whilst works are underway, and by choosing Cwtch Haus to oversee your project, you can relax in the knowledge that everything is taken care of and that your bespoke bathroom will be well planned and installed with minimum disruption.
Eco-Friendly bathroom design
At Cwtch Haus, we love designing sustainable bathrooms and can incorporate eco-friendly features such as water-saving toilets and taps, smart showers, and energy-efficient lighting, helping you to reduce consumption without sacrificing style.
In our Project 258, we installed an Aqualisa smart shower to provide energy efficiency and cost savings for our client.
Aqualisa smart showers are great for saving energy as they have an Eco Mode, which reduces water flow by up to 33%. If you choose an Aqualisa smart shower, you can then download the Aqualisa App, which allows you to track your water usage and costs, encouraging you to take shorter showers, helping to reduce your overall energy bills.
Further cost savings are also possible if you go for a compatible water-saving showerhead.
As part of your Cwtch House design consultation, we can guide you through a number of eco-friendly bathroom options, such as the Aqualisa smart shower.
