How Much Does an En Suite Bathroom Cost in Glasgow?

What An En Suite Costs In Glasgow

An en suite is usually the smallest bathroom in the house, but it is not always the cheapest. The price depends far less on the size of the room than on one question: is there an en suite there already?

If there is, and you are replacing what you have, most Glasgow en suites fall in the same band as our shower rooms: £3,500 to £5,500 fitted. That covers stripping out the old room, a new shower enclosure and tray, a toilet, a basin or vanity unit, wall panels or tiling, flooring and making good.

If all you want is a new shower enclosure in the same spot, with the rest of the room left alone, that is a smaller job at around £1,200 to £2,200.

If you are carving a new en suite out of a bedroom or a box room, there is no honest single figure. Everything depends on how far the new room sits from the existing drains, and that can only be judged by looking at the house.

Refit, Wet Room Or Brand New: The Figures

These figures match the ones in our guide to shower room costs in Glasgow, because an en suite is, in practical terms, a shower room with a bedroom door.

Type of job	Typical cost	Time on site
Shower enclosure swap, same position	£1,200 to £2,200	2 to 3 days
Full refit of an existing en suite	£3,500 to £5,500	3 to 6 days
En suite converted to a level-access wet room	From around £5,500	3 to 6 days
Brand new en suite where there was none	Priced after a survey	Depends on the building work

For comparison, a full family bathroom in Glasgow typically lands between £5,500 and £8,000 fitted. An en suite usually comes in under that because there is no bath, less wall to cover and less floor to lay.

What Drives The Price Of An En Suite

• Drainage. The toilet has to connect to the soil stack, the large vertical waste pipe that serves the house. The further the en suite is from it, the more floor has to come up. Where a normal connection is not practical, a macerator (a small pump unit behind the toilet) can do the job, but it is noisier and needs power, so it is a last resort.
• Water pressure. A good shower upstairs depends on your hot water system. A combi boiler or a pressurised cylinder usually copes well. An older tank-fed system may need a pump, or an electric shower instead.
• Wall finish. Wet wall panels go up faster than tiles and have no grout to go mouldy, which suits a small room that steams up quickly. Full-height tiling takes longer and costs more in labour.
• Building the room. A new en suite needs a stud wall, a door, sound insulation, lighting, heating and an extractor fan before any bathroom fittings go in.
• Ventilation. Many en suites have no window, so the fan has to be ducted to the outside. A long duct run through a loft or across a ceiling adds time.
• The fittings you choose. Enclosures, taps, showers and vanity units vary widely in price. This is the part of the budget you control most easily.

Keeping the toilet and the shower waste where they already are is the single biggest saving on any en suite refit.

Making A Small En Suite Work

Most en suites are tight, and a good layout matters more than expensive fittings. These choices make the biggest difference.

• A sliding door, a bi-fold door or a fixed walk-in screen. Nothing swings out into the room, so the toilet and basin can sit closer to the shower.
• A corner (quadrant) tray. The curved front gives back floor space in a square room.
• A short-projection toilet and a slim vanity unit. Both are made for small rooms and stick out less from the wall.
• Storage in the vanity and a mirrored cabinet. It keeps the surfaces clear, which makes a small room feel bigger.
• A heated towel radiator. It heats the room and dries the towels without taking up floor.
• A door that opens outwards or slides. In a very small en suite this can be what makes the layout possible.

A designer helps you plan the layout during the visit, and you can see enclosures, trays and wall panels side by side at our showrooms. Our modern bathrooms page shows the clean, simple look that tends to suit a small en suite best.

En Suites In Glasgow Homes

Newer estate houses. Many homes built around the city in the last few decades came with an en suite off the main bedroom. They are often small, with a tight enclosure and basic fittings, but the drainage and ventilation are already in place. These are the simplest and most predictable refits.

Tenements and sandstone flats. These rarely have an en suite, and adding one is a bigger project. The soil stack is shared with the rest of the close, the floors are timber and often need strengthening, and you may need to speak to your factor before pipework is altered. It can be done, but it needs planning.

Loft and attic bedrooms. The sloping ceiling decides the layout. The shower goes where the headroom is highest, and the toilet or basin can tuck under the slope. A roof window helps with daylight, but you still need a fan.

Ventilation, Electrics And Building Standards

A like-for-like refit of an existing en suite does not normally involve the council. Creating a new one can. In Scotland, work such as new drainage connections, new partition walls or alterations inside a flat may need a building warrant, and the work has to meet the Scottish Building Standards whether or not a warrant is needed. The rules depend on the property, so check with your council's Building Standards team before work starts.

If your home is listed or in a conservation area, speak to the planning department too, particularly about any new vent or pipe on an outside wall.

Every en suite needs proper ventilation, and a room with no window relies entirely on its extractor fan. Our guide to bathroom ventilation in Scotland explains what to look for. Electrical work in a bathroom should be done by a qualified electrician who gives you a certificate for it, and anything involving a gas boiler is a job for a Gas Safe registered engineer.

How Long It Takes And Ways To Pay

We fit bathrooms in 3 to 6 days, and an en suite refit usually sits towards the shorter end. If a new en suite needs a wall built and drainage run first, that building work comes before the bathroom fit and adds to the overall time.

The advantage of an en suite project is that the main bathroom stays in use throughout, so the household is never without a toilet or a shower.

If you would rather spread the cost, finance is available from £22 a week, subject to status. The details are on our finance page. Various deposit options are available. All workmanship is guaranteed, and the work is carried out by trusted installers.

Quick Answers

How much does an en suite cost in Glasgow?

A full refit of an existing en suite typically costs £3,500 to £5,500 fitted. A shower enclosure swap alone is around £1,200 to £2,200, and a level-access wet room en suite starts around £5,500.

Is an en suite cheaper than a full bathroom?

Usually, yes. A full bathroom in Glasgow typically costs £5,500 to £8,000. An en suite has no bath and less wall and floor to cover, so a refit normally comes in below that.

Can I add an en suite to any bedroom?

Not always. It depends on whether the toilet and shower can drain to the soil stack, whether the hot water system can supply a second shower and whether a fan can be ducted outside. A survey answers all three.

Do I need a building warrant for a new en suite in Scotland?

You may do, particularly where new drainage or new walls are involved, or the property is a flat. Replacing an existing en suite like for like normally does not. Confirm with your council's Building Standards team.

Does an en suite need a window?

No, but it does need mechanical ventilation. A room without a window relies on an extractor fan ducted to the outside air.

How long does an en suite take to fit?

We fit bathrooms in 3 to 6 days, and a straightforward en suite refit is usually at the shorter end of that.
