Adding or upgrading an en-suite is the most popular bathroom project in Edinburgh right now. In tenement flats, it often means squeezing a shower, toilet, and basin into the corner of a bedroom. In larger homes, it is about creating a private retreat. Either way, getting the layout right in a small space is everything. Here is what works.
Can You Add an En-Suite in an Edinburgh Tenement?
This is the most common question we get asked. The short answer is yes — but it depends on a few practical factors that are specific to Edinburgh tenement buildings.
Soil stack proximity. The toilet needs to connect to the building's shared soil stack (the main waste pipe). If your bedroom wall backs onto the existing bathroom or kitchen, the soil stack is usually within reach. This is the single biggest factor in whether an en-suite is feasible in your flat.
Plumbing routes. Supply pipes (hot and cold water) are flexible and can be routed through floor voids and wall cavities without too much difficulty. Waste drainage is the constraint — it needs gravity. The toilet waste pipe must fall at a minimum gradient to the soil stack, and distance matters. The further from the stack, the more floor height you may need to accommodate the pipe run.
Building warrant. Adding a new en-suite where one did not previously exist requires a building warrant from City of Edinburgh Council. This is not optional. We handle the application process as part of the project, so you do not need to navigate it yourself.
Space needed. The minimum practical en-suite is approximately 1.2m x 1.6m. That gets you a walk-in shower, wall-hung toilet, and compact basin. It is tight, but it works — and we fit en-suites this size in Edinburgh tenements regularly.
Sound insulation. An en-suite shares a wall with a bedroom, which means noise matters — especially at 6am. We use acoustic insulation behind wet wall panels and sound-reducing waste pipes to minimise the sound of flushing and running water.
En-Suite Layouts That Work in Small Spaces
Shower at the back, toilet in the middle, basin by the door. Everything in a line. This works in a narrow space carved from a bedroom corner and is the most common layout we fit in Edinburgh tenement en-suites. Simple, efficient, and surprisingly comfortable when the fixtures are well chosen.
Shower in the corner, toilet and basin on the adjacent wall. This makes better use of space than a linear layout and allows for a larger shower area. Works well in Edinburgh properties where a bedroom corner can give you a slightly wider footprint.
No shower tray — the entire floor is tanked and graded to a drain. This saves space (no tray edge to step over), makes the room feel bigger, and is the most practical option for very small en-suites under 2 square metres. The seamless finish also makes cleaning straightforward.
A standard door swing into a small en-suite wastes roughly 30% of the floor space. A sliding pocket door or barn-style slider eliminates this problem entirely. We recommend this for every small en-suite — it is one of the simplest changes that makes the biggest difference to usability.
Wall-hung toilet and basin free up floor space and make cleaning easier. In a small en-suite, every centimetre of visible floor makes the room feel larger. Wall-hung fixtures also give a cleaner, more modern look that suits the compact proportions.
Design Tricks for Small Edinburgh En-Suites
Getting the layout right is step one. The finishes and details are what make a small en-suite feel like a proper room rather than a cupboard with plumbing.
- Light wet wall panels in marble or stone effect (cream, white, soft grey) — these reflect light and create the illusion of more space. Dark panels look dramatic in large bathrooms but close in a small one.
- Large-format panels with minimal joins — fewer visual breaks make the room feel bigger. A single panel running floor to ceiling reads as one continuous surface.
- Continuous LVT flooring in the same colour from bedroom threshold through the en-suite — this creates visual flow between rooms and eliminates the hard line that makes a small room feel separate and boxed in.
- LED mirror — the ambient glow makes a small, internal room feel less claustrophobic. Essential in en-suites with no window, which is most of them in Edinburgh tenements.
- Glass shower screen (not a curtain) — a see-through screen does not interrupt sightlines. A curtain or frosted screen visually cuts the room in half.
- Recessed storage niche in the shower wall — saves having a shelf unit or caddy taking up space. Built into the wet wall during installation, it sits flush and keeps bottles tidy.
En-Suite Upgrades for Existing Edinburgh Bathrooms
Not every en-suite project is a new build. If you already have an en-suite but it is dated, a wet wall and LVT refresh transforms it completely. Most existing en-suites in Edinburgh were fitted in the 1990s or 2000s with basic tiles, grouted walls, and a plastic shower cubicle. They look tired and they are harder to keep clean than they should be.
Replace the bath-with-shower with a proper walk-in. This is common in 2-bed Edinburgh flats where the en-suite has an unnecessary small bath that nobody uses. Removing it and fitting a walk-in shower doubles the usable space and makes the room feel dramatically different.
Modern fixtures. Matte black or chrome thermostatic shower, wall-hung toilet, compact vanity basin with storage underneath. These are not just aesthetic upgrades — wall-hung fixtures genuinely make a small room more functional.
LED mirror with demister. Essential in internal en-suites with no window. The demister means no wiping condensation every morning, and the LED light means no overhead spotlight casting harsh shadows.
En-Suite Costs in Edinburgh
Every en-suite is different, but here are realistic starting points based on projects we complete in Edinburgh regularly:
- Existing en-suite renovation (like-for-like replacement with wet walls, LVT, new fixtures): from £3,699 (our Starter package)
- En-suite upgrade with layout changes (moving fixtures, improving the shower, changing the door): from £5,499 (Premium package)
- New en-suite added to a bedroom: from £5,499 to £7,995+ depending on plumbing distance from the soil stack, floor preparation, and building warrant requirements
- 0% finance from £67/month available on all options — no deposit required
- Building warrant fee (if applicable): approximately £150–£250 via City of Edinburgh Council
All our packages include design, all materials, professional fitting, LVT flooring, LED mirror, and rubbish removal. The price we quote after a home visit is the price you pay — it does not change.
Adding Value to Your Edinburgh Property
A second bathroom or en-suite is consistently the most valuable improvement for Edinburgh 2+ bedroom flats. It is not just about convenience — it directly affects what buyers will pay.
- Estate agents report that en-suites add £5,000–£15,000 to Edinburgh property values depending on area and property type
- In competitive EH3, EH9, EH10, and EH12 markets, a master en-suite is increasingly expected in 3+ bedroom properties
- Even a compact, well-designed en-suite adds more value than a loft conversion in many Edinburgh properties
- For buy-to-let landlords, an en-suite bedroom commands significantly higher rent — particularly in EH1, EH3, and EH6 where demand for quality flats is strongest
The return on investment is clear. A £5,499 en-suite installation that adds £10,000+ to your property value is one of the most straightforward home improvements you can make.
