If you have been living in West Sussex for any length of time, you know that our homes, whether they are charming period cottages in Arundel or modern builds in Chichester, eventually reach a point where the bathroom feels a little tired. Perhaps the grout is starting to fail, the shower pressure isn’t what it used to be, or the layout simply doesn't suit your lifestyle anymore.
When you decide it’s time for a change, the first question is usually: "What is actually included in a bathroom refurbishment?" It sounds simple, but a professional refurbishment is far more than just "swapping a tub for a shower." It is a complex orchestration of trades, materials, and technical standards.
At Swanbourne Construction Ltd, we believe that the best bathroom design West Sussex has to offer shouldn't just look beautiful on day one, it should function perfectly for decades. To help you plan your next home improvement project, here is a complete breakdown of what goes into a professional bathroom refurbishment.
1. The Strip-Out and Structural Preparation
The first phase of any refurbishment is the most disruptive but arguably the most important. We don't just "tile over" old problems. A true refurbishment starts with a total strip-out of the existing space.
- Removal of Old Fixtures: This includes the toilet, basin, bath, and shower tray.
- Hacking off Old Tiles: We take the walls back to the original substrate (brick or stud work) to ensure a perfectly flat surface for new finishes.
- Floor Inspection: We check the joists for any signs of rot or water damage, which is common in older West Sussex properties where leaks may have gone unnoticed for years.
- Disposal: Professional waste management, ensuring that old materials are disposed of responsibly.
By starting with a blank canvas, we can identify and fix structural issues before they become expensive problems later down the line.
2. Plumbing: The Invisible Infrastructure
Once the room is empty, the "first fix" plumbing begins. This is where the layout of your new bathroom is truly born.
- Pipework Re-routing: If you are moving the position of your vanity or toilet, we install new hot and cold feed pipes and waste pipes.
- Shower Valve Installation: We install the internal components of your shower, the valves that sit behind the wall.
- Pressure Testing: Before any walls are closed up, we pressure-test the system to ensure there are zero leaks.
We pay particular attention to drainage. In many older homes in Bognor or Chichester, original drainage wasn't designed for high-flow modern rainfall showers. We ensure your plumbing is up to the task.

3. Electricals and Lighting
Electricity and water don't mix, which is why bathroom electrics are governed by strict safety regulations (specifically "zones"). A professional refurbishment includes:
- Lighting Design: Moving away from a single central bulb to layered lighting. This might include recessed LED spotlights, mood lighting in niches, or backlit mirrors.
- Extraction and Ventilation: A critical component often overlooked. We install high-performance extractor fans to prevent steam build-up and mould.
- Underfloor Heating: For that touch of luxury on a cold West Sussex morning, electric or water-based underfloor heating is installed before the tiles go down.
- Shaver/Toothbrush Points: Discreetly hidden or integrated into cabinets for a clutter-free look.
4. Waterproofing (The "Tanking" System)
If you ask us what the most important part of bathroom design West Sussex is, we won't say the tiles; we will say the waterproofing.
At Swanbourne Construction Ltd, we employ a full "tanking" system in all wet areas. This involves applying a waterproof membrane to the walls and floor of the shower area. Even if a grout line eventually cracks, the water cannot penetrate the structure of your home. This attention to detail is what separates a DIY job from a professional Swanbourne installation.
5. Wall and Floor Finishes: Tiling
This is where the transformation becomes visible. Whether you’ve chosen large-format porcelain, intricate mosaics, or natural stone, the quality of the finish depends entirely on the preparation of the surface.
- Subfloor Preparation: We ensure the floor is reinforced and level to prevent tiles from cracking over time.
- Tiling and Grouting: Our tilers focus on symmetry and "set-outs," ensuring you don't end up with awkward, thin slivers of tile in the corners.
- Expansion Joints: Essential for preventing tiles from lifting as the house moves and breathes with the seasons.

6. The "Pretty" Bits: Brassware and Sanitaryware
With the tiling complete, we move into the "second fix" phase. This is where the items you actually interact with are installed.
- Sanitaryware: Fitting the toilet (back-to-wall, wall-hung, or close-coupled) and the basin.
- Brassware: This refers to your taps, shower heads, and controls. Whether you prefer a modern matt black or a classic brushed gold, these are the "jewellery" of the bathroom.
- The Bath/Shower Screen: Installing the final glass partitions and ensuring all seals are watertight.
7. Vanity Units and Storage
A bathroom that looks good but has nowhere to put your spare towels or toiletries isn't a successful design.
- Vanity Units: We install wall-hung or floor-standing units that house the basin and provide essential storage.
- Integrated Storage: This might include recessed shelving (niches) inside the shower area, which we construct during the framing stage.
- Mirrors: Often featuring demister pads and integrated lighting to make your morning routine easier.
8. Final Commissioning and Finishing Touches
The last 5% of a project takes 100% of the focus. Our team doesn't consider a job finished until the details are perfect.
- Silicone Sealing: Using high-grade, mould-resistant silicone to create clean, flexible seals around all joints.
- Decoration: Painting the ceiling and any non-tiled walls using specialized bathroom paint that resists moisture.
- Accessories: Fitting towel rails, toilet roll holders, and robe hooks exactly where you want them.
- Testing: We run every tap and flush every toilet multiple times to ensure the system is perfect.

Why Swanbourne Construction Ltd?
You might wonder if all these steps are necessary. Could you skip the tanking? Could you leave the old pipes where they are? Technically, yes: but you’d be gambling with your home.
As expert builders in Chichester and the surrounding areas, we have seen the results of "shortcuts." We’ve been called in to fix bathrooms that are only two years old because the waterproofing failed or the plumbing wasn't vented correctly.
Our approach is different. We combine professional technical expertise with a casual, stress-free experience for you. We manage the entire process, from the first sledgehammer blow to the final polish of the taps. Our reputation for attention to detail is built on the fact that we treat your home like our own.
Investing in Quality
A bathroom refurbishment is a significant investment. According to various UK housing studies, a high-quality bathroom can add between 4% and 5% to the value of your property. In the competitive West Sussex property market, a beautifully designed, professionally installed bathroom makes your home stand out.
But beyond the financial return, there is the quality of life factor. Imagine waking up and walking into a space that feels like a luxury spa: a space where everything works, the floor is warm, and the design reflects your personal style.
Whether you are looking for extensions in Chichester that include a new master suite, or you simply want to breathe new life into an existing family bathroom, we are here to guide you.
