En-Suite Bathroom Design and Installation
An en-suite bathroom is no longer a luxury — it’s almost expected in any Glasgow property at £350k+. We deliver en-suites in three core scenarios: replacing dated en-suites in existing master bedrooms, adding new en-suites to bedrooms that don’t currently have one, and upgrading builder-spec en-suites in modern executive new-builds.
En-Suite Layout Designs Under 4m²
Compact en-suites are an art form. The most common Glasgow en-suite footprint is 1.8 to 2.5 metres wide by 1.6 to 2.2 metres deep — under 4 square metres. Layouts that work:
- Linear arrangement — shower at one end, WC in middle, basin at other end. Simple, cheap, works
- Corner shower configuration — quadrant or square corner shower, frees up wall space for WC + basin
- Walk-in shower with screen — takes more space but feels much larger; suits 2.5m+ width
- Slimline vanity with semi-recessed basin — saves 100–150mm of depth vs traditional
- Sliding door entry — saves 800mm vs swinging door
Adding an En-Suite to an Existing Bedroom
- Feasibility assessment — can waste pipe reach existing soil stack? Is there enough space (minimum 4m² for any usable en-suite)?
- Building Control notification — required for new bathrooms; we handle
- Stud walling — partition new en-suite from bedroom, typically 75mm or 100mm stud
- First fix services — plumbing, electrical circuits, ventilation routing
- Boarding and tanking — aquaboard or moisture-resistant; full waterproof membrane to wet zones
- Tiling, sanitaryware, second fix, finish — standard from there
Plumbing Considerations
- Soil pipe routing — en-suite waste must reach the main soil stack; gravity drainage usually requires the WC within 6m horizontal of the stack
- Saniflo / macerator pumps — used where gravity routing isn’t possible; reliable but require power and create noise
- Water pressure — combi boiler systems usually fine for one en-suite; large family homes with multiple bathrooms may need a system or unvented cylinder
- Bath vs shower drainage — baths use 40mm waste, showers can use 50mm for better flow
Building Regulations for En-Suites
- Notification under Building (Scotland) Regulations — new bathroom requires Building Warrant
- Ventilation — mandatory mechanical extraction (15 l/s minimum)
- Electrical zones — specific IP-rated fittings required in zones 0, 1, 2
- Glazing safety — toughened glass required in shower screens
- Drainage — trapped wastes, vent pipe, no shared drainage with adjacent properties
Cost Breakdown
| Project | Cost | Time |
|---|---|---|
| Replace existing en-suite (mid-range) | £5,500 – £9,500 | 7–10 days |
| Add new en-suite to existing bedroom | £8,000 – £14,000 | 10–14 days |
| Luxury master en-suite (freestanding bath, walk-in shower) | £15,000 – £28,000 | 14–18 days |
| Compact en-suite (under 3m²) | £5,500 – £8,500 | 7–9 days |
| Premium en-suite with bespoke vanity | £12,000 – £22,000 | 12–16 days |
Compact Storage Solutions
- Wall-hung vanity with internal drawers — doubles capacity vs cabinet doors
- Mirror cabinet over basin — recovers space lost to mirror alone
- Tiled niche in shower — built into wall, holds shower products without protruding
- Slim wall cabinet over WC — uses dead space, holds towels and supplies
- Tall slim cabinet at end of vanity — great for cleaning supplies
Master vs Guest En-Suite Differences
Master en-suite — usually 5–10m², often features both bath and shower, double basin where space allows, premium finishes throughout, sometimes a separate WC compartment. Investment: £12k–£28k.
Guest en-suite — usually 3–5m², shower only (no bath), single basin, mid-range finishes, more practical than premium. Investment: £5k–£10k.
Common Glasgow Housing Types and En-Suites
- Modern executive (Newton Mearns, Bearsden new-builds) — usually have builder-spec en-suite already; renovation focuses on premium upgrade
- 1930s detached/semi-detached — often need en-suite added; typically achieved by carving from large master bedroom
- Victorian villa — can be challenging due to room sizes and waste routing; often best added in newer rear extension
- Period tenement flat — usually impractical due to single bathroom layout and shared soil stacks
FAQ
What’s the minimum size for a usable en-suite?
Around 1.5m x 2m (3m²) for a basic shower-only en-suite. Anything smaller feels cramped. 4m² gives much better usability.
Do I need planning permission to add an en-suite?
No — internal alterations are permitted development. Building Warrant is required and we handle the notification.
Will adding an en-suite add property value?
Almost always — especially in family homes at £350k+. Estate agents consistently rank en-suites as one of the top value-add features. Budget £8–12k typically returns £10–15k in property value plus saleability.
How long is the installation?
7–14 days for replacement; 10–14 days to add new from scratch; 14–18 days for luxury master.
