HomeDecorZone has been fitting bathrooms across Glasgow for over twelve years. Bathrooms look simple from the outside — strip out, tile, plumb in, done. In practice they are the most variable room in any house, because everything depends on what is hidden in the walls and floor before we start. This page is the honest guide we use ourselves before we even quote. We hold 9.62/10 on Checkatrade and 4.8/5 across 277 reviews on MyBuilder, which we think reflects the fact that we tell people what they need to hear rather than what closes a quick sale.
The single biggest planning decision: where the soil and waste run
Before anything else — before tiles, before suite choice, before you fall in love with a freestanding bath — find out where the soil stack and main waste run are. This decides almost everything about what is realistic in the room.
Older Glasgow properties (tenements, 1930s semis, sandstone villas)
Moving the WC or rearranging the layout is genuinely difficult here. Soil pipes are typically cast iron, runs are tight, and the building fabric is solid masonry. To shift a toilet two metres along the wall we usually have to chase the floor (sometimes lift floorboards in the room below), bring waste with proper fall back to the existing stack, and run new water feeds through walls that need cutting open. This is not impossible — we do it regularly across Bearsden, Milngavie and Glasgow’s older areas — but it adds days of labour, mess and making-good. We will tell you honestly during the survey whether the move is worth it for the layout you want, or whether you should plan around the existing connections.
Newer-build Glasgow homes (post-2000, plasterboard construction)
Much more forgiving. Modern construction uses plasterboard on stud walls with hollow service voids behind, which means we can run new water feeds and re-route waste with far less destruction. Moving the WC, basin or shower a metre or two becomes a relatively easy day’s work rather than a week. The same building method also opens up one of our favourite features — built-in shower niches (also called recessed shower shelves), the inset shelves you see in modern showers for shampoo and shower gel. In plasterboard walls these are straightforward to design in. In a solid masonry wall you cannot just cut a pocket — you would need to build out a small stud wall in front of the original masonry, which loses you about 100–150mm of floor area but gives you the niche, plus the chance to hide all the pipes properly behind it.
Ventilation: the most under-spec’d thing in Glasgow bathrooms
You need a proper extractor fan. Even if you have an opening window. Especially if you have an opening window — because in a Glasgow winter (and let’s be honest, a Glasgow summer too) nobody actually opens the bathroom window after every shower. Steam settles into grout, plaster, silicone and the back of cabinets. Within twelve to eighteen months without proper ventilation you start seeing black mould in the corners, around the shower screen, behind the WC, on the ceiling above the bath. Once it is into the grout it is extremely hard to get out.
We always spec a humidity-sensing extractor fan ducted properly to outside (not just into a loft void where the moisture has nowhere to go), with a timed overrun so it carries on running after the light goes off. It is not expensive at install — perhaps an extra hundred pounds in labour and fittings — and it is the single best decision for the long-term life of the room.
Heating: floor, towel rail, or both?
How you heat the bathroom depends on the size of the room, not on what’s fashionable on Instagram.
- Small bathroom (under ~4m²): pick one — either an electric underfloor heating mat OR a heated towel rail. Not both. Two heat sources in such a small space will genuinely turn it into a sauna.
- Medium bathroom (4–7m²): still usually one or the other. Most clients go with the heated towel rail because it dries towels as well as warming the room. Underfloor heating is the luxury option but on its own it can be slow to bring the room to temperature on a cold morning.
- Large bathroom (8m²+): here you can sensibly have both — underfloor heating across the whole floor for ambient warmth, and a heated towel rail for towel-drying duty. Wired on separate thermostats so you control them independently and don’t end up overheating the space.
Showers, shower trays and wet-room conversions
Two important decisions here, and both come back to waste access.
Shower screen height. Standard 1900mm shower screens fit most rooms, but in older tenements with lower ceilings or boxed-in pipework above we sometimes have to spec a 2000mm or 2100mm screen to look right against the wall tiling. We always check this on the survey because nothing looks worse than a shower screen finishing 200mm below the start of the tile run.
Wet room or shower tray? A proper wet room — fully tanked floor, level access, linear drain — looks brilliant and is genuinely the most accessible option (no step over a tray). The catch is the waste. To get a level-access floor you need to drop the joists or build up the surrounding floor, and you need the waste to run away from the drain with proper fall toward the soil stack. If the drain has to travel a long way through a tight floor void you may need to box in the floor or accept a step. Sometimes it just isn’t worth the cost compared to a sleek 25mm-thick low-profile shower tray that achieves a similar look for far less work. We tell you which one fits your house properly — we don’t push wet rooms because they look good on a brochure.
How we usually work — from first quote to handover
Our process is straightforward and we put it in writing every time:
- You contact us — phone, WhatsApp or the quote form on this site. We arrange a free in-home survey, usually within a week.
- We survey, measure, and talk through what you actually want. We will tell you honestly what fits, what we would not do, and where you could save money without compromising the result.
- You buy the suite, tiles and fittings yourself — if you have done your research and you know which Vitra suite, Italian porcelain tiles or Hansgrohe brassware you want, you order it and we fit it. You own the supply side and the pricing.
- Or we help you order — if you would rather not navigate the trade counters and showrooms alone, we send you direct links to the suppliers we use regularly (Tile Giant, City Plumbing, Tap Warehouse, Bathroom Mountain) and we walk you through what to spec.
- Or we order everything for you — full project management. We buy the suite, tiles, brassware, fan, lighting and consumables on our trade accounts, and you get one invoice covering supply and fit. Often slightly cheaper than retail because of trade margins, and considerably less hassle.
The same three options apply to kitchen projects. Whichever feels right for you is the one we run with — we have no preference.
Indicative pricing for a Glasgow bathroom renovation
| Type of Bathroom Project | Typical Cost (labour + materials) | Timeframe |
|---|---|---|
| Standard renovation (mid-range materials, same layout) | £5,000 – £9,000 | 7–10 days |
| Layout-change renovation (moving fixtures, rerouting waste) | £8,000 – £14,000 | 10–14 days |
| Luxury master bathroom (premium suite, freestanding bath, walk-in) | £13,000 – £20,000 | 12–18 days |

Premium suburbs like Newton Mearns, Bearsden and Milngavie usually sit at the higher end of each band because the spec tends to be more ambitious. Clarkston, Giffnock and surrounding East Renfrewshire areas typically land mid-range. We quote fixed-price after the survey — no day rates, no surprises.
