Most complete bathroom installations in 2026 take between four and six weeks, depending on size, complexity and any surprises uncovered once walls and floors are opened up. Below, we break down each stage in detail so you know exactly what to expect.
Planning and design phase
Design consultation and site survey
First, we schedule a consultation at your home in Glasgow or the surrounding area. During this visit, we:
- Measure the space and assess existing plumbing and electrics
- Discuss your style, layout and accessibility needs (for mobility solutions see our mobility and accessible bathroom solutions for scotland homeowners in 2026)
- Recommend modern layouts or small-bathroom ideas (small bathroom renovation ideas for scotland homes in 2026)
- Advise on design trends you’ll love (modern bathroom design trends scotland homeowners are loving in 2026)
This survey usually takes one to two hours, and we follow up with detailed floor plans and mood boards within two to three days.
Finalising designs and selecting materials
Once you’re happy with the layout, we finalise:
- Tile or wet-wall choices (compare in our wet wall vs tiles which is the better choice for your bathroom in 2026)
- Sanitaryware, baths and showers (see our walk in showers and enclosures the 2026 buyers guide for modern scotland homes)
- Vanity units, storage and accessories
- Budget parameters (for detailed cost guidance check bathroom renovation costs in scotland what to expect in 2026)
Material ordering lead times can range from three days for stock items to three weeks for bespoke products. We recommend locking in selections as early as possible to stay on schedule.
Permissions and regulations
In Scotland, minor bathroom remodels rarely need planning permission, but a building warrant is often required if you:
- Alter drainage or install a new shower tray
- Move walls or enlarge the room
- Change heating configuration or ventilation
Applying for a warrant typically takes one to two weeks. We can handle paperwork on your behalf to keep your project moving.
Preparation and demolition stage
Site setup and protection
Before any work begins, we:
- Protect floors and walls in adjacent rooms with dust sheets and corner guards
- Seal doorways to contain dust
- Position skips and waste bins
This setup usually takes half a day and helps us maintain a clean workspace and protect your home.
Removing existing fittings
Next, we strip out your old bathroom:
- Disconnect and remove bath, shower, basin, WC and tiles or wet wall panels
- Dispose of waste responsibly
Demolition and removal typically take one to two days, depending on the size and complexity of your current layout.
Structural adjustments
If your new design requires:
- Moving non-load-bearing walls
- Opening up for a larger shower or wet room
- Installing support for heavy fixtures
This work can add one to two days. Structural changes must meet building warrant requirements and may involve inspections by local authorities.
Installation and fitting stage
Plumbing and electrical first fix
Our plumbers and electricians install the hidden infrastructure:
- New pipe runs, waste outlets and shower feeds
- Rough-in for basin, WC and bidet
- Cables for lighting, heated towel rails and extractor fans
First-fix work usually takes two to three days. We follow the latest guidance on plumbing and electrical requirements for a safe bathroom installation in 2026.
Wall and floor prep
With services in place, we prepare surfaces to ensure a long-lasting finish:
- Level and screed floors
- Apply waterproof membrane or tanking slurry
- Board walls or install cement backer boards
Allow one to two days for full curing before tiling or wet walling begins.
Wet wall or tiling installation
Tiling or fitting wet wall panels is the most visible stage of the renovation:
- Tile layouts for floor and walls, with grout applied after 24 hours
- Wet wall panels cut and sealed around fixtures
Expect two to five days here depending on the pattern complexity, grout curing times and room size.
Fixtures and fittings phase
Bath and shower installation
We fit your chosen bath, shower tray or wet-room underfloor drain:
- Level and secure bath or tray
- Connect overflow, waste and shower valve
This stage takes one to two days, especially if you’re upgrading to a frameless walk-in shower or a bespoke freestanding bath.
Vanity units and storage
Next, we install cabinets, vanity units and shelving:
- Secure to walls with appropriate fixings
- Cut worktops and integrate basins
One day is usually enough for standard units; bespoke joinery may add extra time.
Toilet and sanitaryware
Finally we fit the WC, bidet or wall-hung pan:
- Secure fittings to floor or stud walls
- Connect flush plates and test operation
This step takes around one day, including pressure testing to ensure there are no leaks.
Finishing touches phase
Painting and decorating
With tiling and plumbing complete, we:
- Seal edges and glaze any exposed grout lines
- Apply high-quality bathroom paint to ceilings and trims
Allow two to three days for painting and full drying before re-installing accessories.
Electrical second fix
Our electrician returns to fit:
- Light fittings, switches and sockets
- Heated towel rails and extractor fans
This usually takes a full day, followed by testing and certification.
Quality checks and snagging
Before we hand over your new bathroom, we:
- Review every fitting against our quality checklist
- Note any minor snags and address them immediately
A thorough snagging process typically takes one day to complete.
Project wrap-up phase
Final inspection and sign-off
We conduct a joint walkthrough with you to demonstrate all features—showing how to operate showers, heated rails and ventilation. We also handle any final building warrant inspections so you receive full compliance documentation.
Handover and aftercare
Once you’re happy, we hand over the project:
- Provide manuals and warranty information
- Offer our aftercare support for any questions or maintenance needs

Frequently asked questions
How long does planning and design usually take?
Typically one to two weeks. This covers design consultations, site surveys and finalising material orders. Early decisions on tiles, fixtures and layouts help keep this phase on schedule.
Can I remain at home during installation?
Yes. Most work is contained, and we use dust-control measures. However, expect some noise during demolition and first-fix plumbing. We’ll coordinate with you to minimise disruption.
What factors can delay a bathroom installation?
Common delays include:
- Custom-order fixtures with long lead times
- Unexpected structural issues once walls are opened
- Weather-dependent waterproofing drying times
We build buffers into our timeline and keep you informed of any changes.
Do I need planning permission for a bathroom renovation in Glasgow?
Most internal bathroom refurbishments don’t need planning permission, but a building warrant may be required for drainage alterations, structural changes or ventilation upgrades.

Look for a team with:
- Proper insurance and certification
