Build Me fits ensuite bathrooms in Dublin homes, from a compact shower room off the main bedroom to an ensuite in a new attic. We plan where the soil pipe runs, how the room is ventilated and what fits the space, then build it in 1 to 4 weeks on site.
Prices include VAT at 13.5%. The distance from the toilet to the soil stack moves the ensuite cost more than most people expect, so we check it before we price.
€5,000 to €10,000 in Dublin
A shower, toilet and basin in a room of up to about 4 m², often an ensuite renovation where one already exists. Our Essential package, €9,307 incl. VAT, covers a full refit at this size. Elsewhere in Ireland a small ensuite costs about €4,000 to €8,000.

€9,000 to €17,000 in Dublin
Adding an ensuite to a bedroom where there was none: a new stud wall and door, new supply and waste pipes, and a toilet linked to the soil stack. It sits in our bathroom-with-a-layout-change range, about €9,000 to €17,000 in Dublin, depending on how far the pipes run.
€12,000 to €22,000+ in Dublin
A level floor laid to falls and fully tanked, with a linear drain and a frameless screen. It suits a narrow ensuite because there is no tray to work around. Our Premium package, €24,176 incl. VAT, includes the tanking system, the linear drain and layout changes.

Adds €6,000 to €12,000
A dormer gives the head height a shower needs, and the soil pipe can often drop into the stack below. An ensuite adds about €6,000 to €12,000 to an attic conversion in Dublin (€12,000 to €20,000 at high spec) and about 2 weeks to the build.

€28,000 to €42,000 in Dublin
Turn an attached garage into a ground-floor bedroom with its own en suite shower room, handy for older parents or guests. The whole conversion costs about €28,000 to €42,000 in Dublin and takes 8 to 10 weeks on site with the shower room.

We invest in top tier tools and equipment to achieve precise finishes, professional craftsmanship and lasting results.
Each phase of your project is led by dedicated specialists who excel in their specific area of expertise.
01
A toilet needs a 110 mm soil pipe falling steadily to the soil stack, so the closer it sits to the stack, the simpler the job. Showers and basins use smaller waste pipes that can travel further. At the first visit we find your stack and check which way the floor joists run, because a pipe runs easily between joists but not across them.
02
If the ensuite is too far from the stack, a macerator behind the toilet grinds the waste and pumps it through a small-bore pipe, and a waste pump does the same for a shower. They work, but you hear them run and they need servicing. The building regulations only allow a macerator toilet where the house also has a toilet that drains by gravity, so we use one when it is the only sensible route.
03
Part F of the building regulations asks for a fan that extracts at least 15 litres a second from a room with a shower or bath. With no window, the fan runs on for about 15 minutes after the light goes off, and the door needs a gap of about 10 mm underneath so fresh air can get in. The duct goes out through a wall or the roof, never just into the attic.
04
Every wet zone is waterproofed before it is tiled. A shower on a tray needs the floor and the walls around it sealed, while a walk-in or wet room ensuite needs the whole floor tanked and laid to falls. Waterproofing and tiles need curing time, so the calendar runs a little longer than our days on site.
05
New lighting, the fan and a mirror light or shaver point, wired by a Safe Electric registered contractor, with the completion certificate. A towel radiator usually connects to the nearest heating pipes, and electric underfloor heating takes the chill off a tiled floor.
06
Carving an ensuite out of a bedroom means a new stud wall, insulated against sound, and a door that opens without hitting the bed or the toilet. A pocket sliding door saves the most space. Then plastering, ceiling painting and a final clean.
In many Dublin semis the box room sits beside the main bedroom and close to the bathroom and soil stack, so the pipes stay short. Converting it gives a roomy ensuite, sometimes with a walk-in wardrobe as well. You give up a bedroom, which matters more in a 3-bed than a 4-bed.
A stud wall across one end of a large bedroom makes a shower room about 1.2 m wide. It works best where that wall backs onto the bathroom or sits over the kitchen, so the pipes stay short. The bedroom needs to be big enough to give up about 2.5 to 3.5 m² and still fit the bed.
Plan it in from the start: the shower under the dormer or the highest part of the roof, the toilet and basin where the ceiling slopes lower. The soil pipe usually drops into the stack on the floor below. In Dublin it adds about €6,000 to €12,000 and about 2 weeks to the attic conversion.
A new partition, plumbing and tiling are internal works. The building regulations still apply in full, and an ensuite that comes with an attic or garage conversion follows the rules for that project.

The rules of thumb we plan to. Every room is measured at the site visit.
A tray is the simplest and cheapest way to put a shower in an ensuite. A level-access wet room costs more because the whole floor is tanked and laid to falls.
Cost in Dublin, incl. VAT
Standard (€14,301 incl. VAT) sits between the two, with full-height tiling and a wall-hung toilet. For more ensuite ideas see walk-in shower ideas, or price your own room with the bathroom renovation calculator.
Most ensuites take 1 to 4 weeks on site: 1 to 2 weeks for a small shower room, 3 to 4 weeks for a new layout or a wet room.
We look at the room, find the soil stack, check the joists and a route for the fan duct, and talk through layout and finishes.

A small ensuite costs about €5,000 to €10,000 in Dublin, including VAT, and about €4,000 to €8,000 in the rest of Ireland. Adding a new ensuite where the layout changes and new pipes run to the soil stack costs about €9,000 to €17,000 in Dublin, and a wet room ensuite about €12,000 to €22,000 or more. Our fixed-price bathroom packages are Essential €9,307, Standard €14,301 and Premium €24,176, incl. VAT. Price your own room with the bathroom renovation calculator.
Usually, yes. The three common spots are the box room next door, a slice of the main bedroom behind a new stud wall, or the attic if you are converting it. What matters most is a route for the toilet's soil pipe to the stack. If gravity won't reach, a macerator can pump the waste, as long as the house also has a toilet that drains by gravity. We check the stack, the joists and a route for the fan duct at the first visit.
A shower, toilet and basin in a line fit in a space about 1.2 m wide and 2.2 to 2.5 m long, so roughly 2.5 to 3 m². An 800 × 800 mm shower tray is the smallest worth fitting; 900 mm or a 1,200 mm walk-in feels far roomier. Leave about 600 mm of clear floor in front of the toilet and the basin. From about 3 to 4 m² the room stops feeling tight. Our small bathroom ideas show layouts that work.
No. An ensuite without a window is fine as long as it is ventilated properly. The building regulations ask for an extractor fan of at least 15 litres a second in a room with a shower or bath. With no window it should run on for about 15 minutes after the light goes off, and the door needs a gap of about 10 mm underneath so air can get in. The duct must go outside, through a wall or the roof.
Most ensuites have a shower only. A standard bath is about 1.7 m long and needs a bigger room, while a shower fits in under a square metre. A walk-in shower with a glass panel makes a small ensuite feel bigger and is easy to clean. Keep the bath in the family bathroom, which is where families with young children use it. See our walk-in shower ideas for ensuite ideas that suit a tight room.
A toilet needs a 110 mm pipe with a steady fall to the soil stack, and it can't easily run across floor joists. If the ensuite is too far away, a macerator fitted behind the toilet grinds the waste and pumps it through a narrow pipe, and a waste pump can do the same for the shower. They are noisier than a gravity toilet and need servicing, and the regulations allow them only where another toilet in the house drains by gravity. Moving the stack itself is priced separately.
Usually 1 to 4 weeks on site: about 1 to 2 weeks for a small shower room, and 3 to 4 weeks for a new layout or a wet room, which needs tanking and curing time. An ensuite in an attic conversion adds about 2 weeks to the attic build. A garage conversion with a bedroom and shower room takes about 8 to 10 weeks.
Not for an ensuite inside your house: new walls, plumbing and tiling are internal works. A protected structure is the main exception. If the ensuite comes with a new dormer, side or rear dormers are exempt up to 30 m³ in total under the 2026 exempted development regulations (S.I. 338 to 344 of 2026). The building regulations still apply in full, including ventilation and drainage, and electrical work needs a Safe Electric completion certificate.
