Small bathroom vs ensuite renovation costs in Ireland (2026), including detailed breakdowns, specification tiers, VAT impact and full project examples.
1. Overview
Bathroom renovation costs in Ireland vary significantly depending on:
- Room size
- Layout retention or relocation
- Waterproofing scope
- Tiling coverage
- Fixture specification
- Drainage complexity
Although ensuites are smaller in floor area, they often include nearly identical technical scope to a small main bathroom.
For 2026 in Ireland, full renovation costs typically fall within:
- Ensuite (3–5m²): €7,000 – €16,000
- Small main bathroom (5–7m²): €9,000 – €20,000
These ranges assume full strip-out and rebuild to modern standards.
2. Why Size Does Not Scale Linearly
Bathrooms contain several fixed-cost elements that do not reduce proportionally with size:
- Demolition and waste removal
- Waterproofing (wet-zone tanking)
- Plumbing connections
- Electrical safety requirements
- Ventilation installation
- Core sanitaryware
As a result, a 4m² ensuite may cost nearly as much as a 6m² main bathroom.
3. Typical Cost Breakdown – Ensuite (3–5m²)
| Component | Typical Cost Range |
|---|---|
| Strip-out & disposal | €400 – €1,000 |
| Plumbing (retain layout) | €1,200 – €3,000 |
| Drainage alterations | €400 – €3,000 |
| Electrical & ventilation | €600 – €1,800 |
| Waterproofing (wet zone) | €800 – €2,500 |
| Tiling (supply + install) | €1,800 – €4,500 |
| Fixtures & sanitaryware | €1,800 – €6,000 |
| Glass enclosure | €350 – €2,500 |
| Joinery / vanity | €300 – €2,000 |
| Finishes & making-good | €200 – €900 |
| Typical Total | €7,000 – €16,000 |
Drainage relocation or concealed fixtures push totals toward the upper end.
4. Typical Cost Breakdown – Small Main Bathroom (5–7m²)
| Component | Typical Cost Range |
|---|---|
| Strip-out & disposal | €600 – €1,400 |
| Plumbing (retain layout) | €1,500 – €4,000 |
| Drainage alterations | €600 – €4,500 |
| Electrical & ventilation | €800 – €2,200 |
| Waterproofing | €900 – €3,000 |
| Tiling (greater wall area) | €2,000 – €6,000 |
| Fixtures & sanitaryware | €2,500 – €7,500 |
| Bath (if included) | €300 – €3,500 |
| Joinery / vanity | €400 – €3,000 |
| Finishes | €300 – €1,200 |
| Typical Total | €9,000 – €20,000 |
Bath inclusion and greater tiling area increase cost compared to ensuites.

11. Summary
Typical 2026 renovation ranges in Ireland:
- Ensuite: €7,000 – €16,000
- Small main bathroom: €9,000 – €20,000
Although ensuites are smaller, fixed-cost elements keep them relatively expensive per m².
Waterproofing, tiling area, and fixture specification are the dominant cost drivers.
