Update your settings

A bathroom renovation is one of the most effective ways to add comfort, value, and visual appeal to your home. Whether you're upgrading a tired ensuite, redesigning a family bathroom, or completely gutting and starting from scratch, proper planning is key. For homeowners in Southampton, working with experienced bathroom designers Southampton has to offer can make the process smoother, faster, and far less stressful.

This step-by-step guide will walk you through every stage of your bathroom renovation—from the first idea to the final finishing touch—ensuring your project stays on budget, on schedule, and on point.

Step 1: Define Your Renovation Goals

Before you even start looking at tiles or fittings, it’s important to define why you're renovating. The more specific you are about your goals, the easier it will be to make decisions along the way.

Ask Yourself:

• Is this renovation for style, function, or both?

• Do I need to update outdated fixtures?

• Am I trying to create a spa-like retreat, a practical family bathroom, or something else?

• Are there plumbing or ventilation issues that need fixing?

Once your goals are clear, it becomes easier to prioritise your budget and make the right design choices.

Step 2: Set a Realistic Budget

Your budget will shape every aspect of the renovation—from layout and materials to lighting and accessories. Bathroom renovations in Southampton typically range from £3,000 to £15,000+, depending on the size and scope.

Include in Your Budget:

• Labour (plumbing, tiling, electrics, installation)

• Fixtures and fittings (toilet, sink, bath, shower, etc.)

• Tiles and flooring

• Lighting and ventilation

• Custom cabinetry or storage solutions

• Unexpected costs (allow a 10–15% contingency)

Consulting with bathroom designers Southampton locals trust can help you build a realistic budget based on your space and goals.

Step 3: Measure and Assess Your Space

Every bathroom is different. Take precise measurements of the space, including the ceiling height, location of existing plumbing and electrical points, and any awkward corners or recesses.

Things to Note:

• Position of doors and windows

• Height and depth of alcoves

• Ceiling angles (especially in loft conversions)

• Accessibility needs for all users

This is where working with professional bathroom designers in Southampton becomes invaluable—they can assess your space, suggest layout improvements, and create detailed plans that maximise functionality and aesthetics.

Step 4: Choose a Layout That Works

Before choosing tiles or taps, you need to decide on a practical layout. Can you keep the existing layout to reduce plumbing costs? Or are you willing to move things around to improve usability?

Popular Layout Considerations:

• Positioning the toilet discreetly (away from the door)

• Using wall-mounted sinks or toilets to save space

• Creating a wet room if space is tight

• Separating the shower and bath if possible

• Ensuring enough space to move comfortably

Many bathroom designers Southampton homeowners work with will use 3D planning tools to visualise different layout options before committing.

Step 5: Select Your Fixtures and Fittings

Fixtures play a huge role in both the look and function of your bathroom. Here’s what you’ll need to choose:

Essentials:

• Toilet: Wall-hung, back-to-wall, or close-coupled?

• Basin and Vanity: Freestanding or integrated?

• Bath: Standard, freestanding, or shower-over-bath combo?

• Shower: Enclosed unit, walk-in, or wet room?

Optional Add-ons:

• Heated towel rails

• Underfloor heating

• Smart mirrors or LED lighting

• Touchless taps

• Storage cabinets or niches

Pro tip: Stick to a consistent style across fixtures for a cohesive look, and consider longevity and ease of maintenance.

Step 6: Pick Materials That Balance Style and Function

When it comes to tiles, countertops, and flooring, aesthetics are important—but so are practicality and durability.

Consider:

• Tiles: Choose large-format tiles for a modern look and fewer grout lines.

• Flooring: Opt for porcelain, vinyl, or natural stone with slip resistance.

• Countertops: Consider quartz, solid surface, or laminate for cost-effective durability.

• Wall panels: A great low-maintenance alternative to tiling in showers.

Many bathroom designers Southampton recommend choosing neutral tones for resale value, adding colour through accessories or accent walls.

Step 7: Lighting and Ventilation

These two often-overlooked elements can make or break your bathroom’s comfort and longevity.

Lighting:

• Ceiling lights for general illumination

• Task lighting near mirrors for grooming

• Ambient lighting for mood (LED strips, dimmers)

Ventilation:

• Always install a high-quality extractor fan to prevent mould and condensation.

• If you have a window, choose treatments that let in natural light without compromising privacy.

Southampton's damp coastal air makes ventilation especially important—experienced bathroom designers Southampton professionals can recommend products suited to the local climate.

Step 8: Hire the Right Professionals

Now that your design is taking shape, it’s time to hire the right people to bring it to life.

You’ll Need:

• A bathroom fitter or contractor

• A qualified plumber

• A certified electrician

• A tiler and decorator

Rather than sourcing all of these individually, consider hiring a full-service bathroom design company in Southampton. They coordinate all trades for you, manage timelines, and often guarantee the work.

Step 9: Prepare for the Renovation

Once your team is booked and materials ordered, prepare your home and schedule.

Preparation Tips:

• Clear out the bathroom and any connecting areas

• Set up a temporary wash station if it's your only bathroom

• Confirm the project timeline and daily access arrangements

• Protect flooring and furniture in nearby rooms

Renovations can be messy, noisy, and slightly disruptive—but the results are worth it!

Step 10: Installation and Final Checks

The renovation usually follows this sequence:

1. Demolition: Removing old tiles, fixtures, and fittings

2. First fix: Plumbing and electrical adjustments

3. Floor and wall preparation: Including waterproofing

4. Tiling and wall finishes

5. Second fix: Installing new fixtures, lighting, and mirrors

6. Final touches: Silicone sealing, paintwork, accessories

Once complete, do a final walk-through with your contractor. Check that everything functions correctly and matches your expectations. Don’t forget to keep warranties and manuals for all fixtures and appliances.

Step 11: Style and Accessorise

Now comes the fun part—styling your new bathroom!

Ideas to Add Character:

• Towels in calming or contrasting colours

• Plants for a fresh, natural vibe

• Soap dispensers and storage baskets that match your décor

• Artwork or a statement mirror to complete the look

If you're unsure how to style your space, many bathroom designers Southampton locals work with also offer interior styling advice to add those final, Instagram-worthy touches.
