Bathroom Renovation in Dublin

A proper bathroom renovation in Dublin involves much more than replacing tiles and fittings. Depending on the project, a full bathroom renovation can include strip-out of the existing room, layout changes, plumbing, drainage, electrical work, ventilation, waterproofing, wall and floor preparation, tiling, sanitaryware, storage, lighting, heating and final finishing.

Coordinating these elements before installation matters because much of the critical work ends up hidden behind tiles, walls and floors. Pipe routes, waterproofing, cabling and extraction need to be right before the visible finishes go on, because correcting them later means taking the finished room apart.

Whether you need a straightforward bathroom refurbishment, a shower installation in Dublin or a bathroom planned as part of a complete house renovation, RSM plans the technical work and the finishes together so the room works as well as it looks.

A good bathroom design starts with how the room will be used and the technical constraints of the space, not with choosing tiles. Getting the layout right first makes every later decision easier.

Moving fixtures can significantly change the plumbing scope, particularly the WC, which depends on its drainage connection. The main points to work through are:

One of the most important parts of a bathroom renovation is invisible once the room is finished. The tiles you see are a decorative, hard-wearing finish. The protection against water sits behind them, in the waterproofing or tanking layer and the prepared surface underneath.

Bathroom waterproofing in Dublin homes is especially important in shower areas and wet rooms, where walls and floors are regularly soaked. Bathroom tanking, where appropriate, creates a continuous protective layer so water that passes through grout joints doesn't reach the substrate or the structure below.

The details matter most at the weak points: junctions between walls and floors, around pipe penetrations and wastes, at the shower tray or drain, and wherever the room changes from wet to dry. Sealing, drainage and moisture management are planned together rather than treated as separate jobs.

The right approach depends on the area, the substrate and the products used, and it should follow the relevant manufacturers' requirements. Because this work is covered over, it needs to be done correctly at the time.

Bathroom plumbing covers the hot and cold supplies to each fixture, the waste connections from the basin, bath and shower, and the WC's connection to the drainage. During a renovation, these are often reviewed and renewed while the walls and floors are open.

Keeping fixtures close to existing services can sometimes simplify a project, while major layout changes can require more extensive pipework and drainage alterations. The condition of existing pipework, the falls available for wastes and water pressure all influence what is practical. Every property is different, so these points are checked rather than assumed.

Bathrooms produce more moisture than almost any other room, so ventilation should be considered as part of every renovation. Without effective moisture removal, condensation can form on cold surfaces and contribute to mould and damage to finishes over time.

Extractor ventilation is the usual solution, and the right approach depends on the room size, its layout, whether there's a window and how the bathroom fits into the ventilation of the wider home.

Irish Building Regulations include requirements relating to ventilation. The appropriate solution depends on the dwelling and the scope of work.

Good bathroom storage keeps surfaces clear without eating into usable floor area. That balance matters most in small Dublin bathrooms and ensuites, where a bulky unit can make the room harder to use.

A successful small bathroom comes from the whole layout working together rather than from a single trick. Tile size, colour or a bigger mirror can help, but only when the layout, fixture proportions and storage are already right.

Compact vanity units and wall-mounted storage free up floor space. Shower glass placement and the door swing decide how easy the room is to move around. Layered lighting, well-placed mirrors and visual continuity across walls and floor make the room feel calmer, and adequate ventilation is essential in a small volume.

Once old tiles, sanitaryware and finishes are removed, conditions that were previously hidden can sometimes become visible. This doesn't happen in every bathroom, but depending on the property, it may include:

Routine internal bathroom refurbishment is generally a different matter from development involving extensions, structural changes, external alterations, material changes or protected structures. Whether consent is needed depends on the property and the proposed work.

Planning permission and Building Regulations are separate matters. Depending on the scope, Irish Building Regulations can be relevant to areas such as ventilation, drainage, electrical work, materials and workmanship.

Protected structures and properties subject to conservation restrictions may require additional consideration, even for internal works. Read our guide to planning permission for home renovations in Dublin for wider context.

Many homeowners can stay in the house during bathroom works, particularly if another working bathroom remains available. If the bathroom being renovated is the only one, there will be periods when it can't be used, and water or electricity may need to be turned off at certain stages.

How practical it is depends on:

Even a relatively small bathroom can involve several coordinated disciplines. Each one usually depends on the previous stage being completed correctly: tiling relies on sound preparation and waterproofing, waterproofing relies on first-fix plumbing being in the right place, and glass is measured only once the tiling is finished.
