Small bathroom and ensuite renovation planning

Small bathroom and ensuite renovation costs in Ireland (2026), including typical breakdowns, specification tiers, tiling, VAT and full project examples.

Ensuite: €7,000–€16,000   |   Small bathroom: €9,000–€20,000

Bathroom Size Does Not Scale Linearly

Bathroom renovation costs vary with room size, layout retention or relocation, waterproofing scope, tiling coverage, fixture specification and drainage complexity.

Although ensuites are smaller in floor area, they still contain many of the same fixed-cost elements as a main bathroom: demolition, plumbing, electrical safety work, ventilation, waterproofing and core sanitaryware.

That is why a 4m² ensuite can cost nearly as much as a 6m² main bathroom.

The typical 2026 full-renovation range is €7,000–€16,000 for an ensuite and €9,000–€20,000 for a small main bathroom, assuming full strip-out and rebuild to modern standards.

Ensuite Renovation Costs

A typical 3–5m² ensuite costs around €7,000–€16,000 for a full renovation.

Plumbing, waterproofing, tiling and sanitaryware remain the largest cost areas despite the smaller footprint.

Drainage relocation or concealed fixtures push costs towards the upper end.

Small Bathroom vs Ensuite

Ensuite (3–5m²)

Typical total: €7,000–€16,000

Common cost drivers are wet-zone tanking, shower enclosure, drainage, tiling and compact joinery.

Because most technical systems are still required, the cost per m² is often high.

Small Main Bathroom (5–7m²)

Typical total: €9,000–€20,000

Higher costs usually come from greater tiling area, larger sanitaryware allowances and the possible inclusion of a bath.

Extra floor and wall area increases both material and labour requirements.

Glass enclosure / bath€350–€2,500€300–€3,500

Finishes€200–€900€300–€1,200
Typical total€7,000–€16,000€9,000–€20,000

A small bathroom generally costs more because it has more wall area to tile and may include a bath, but the difference is smaller than the floor-area difference might suggest.

Bathroom tiling and finishes

Tiling Area Matters More Than Floor Area

A typical 4m² ensuite may have 19–29m² of total tiled area.

A 6m² small bathroom may have around 26–41m² of total tiled area.

Installed tiling typically ranges from €60–€160 per m² depending on tile type and complexity.

High-end wet-room style bathroom€20,000€2,700€1,400€24,100

Budget specifications generally use standard sanitaryware and simpler tiling, while high-end projects can include concealed cisterns, premium stone, wet-room tanking, designer fittings and bespoke joinery.

VAT

The current page distinguishes between construction labour, retail-supplied fixtures and professional services.

VAT treatment can materially change headline comparisons, so confirm whether quoted totals include VAT and how supplied materials are treated.

Timeline

Basic ensuite: 2–3 weeks
Mid-range bathroom: 3–4 weeks
Wet-room / complex: 4–6+ weeks

Layout changes and more complex waterproofing extend programme length.

Primary Cost Drivers

Drainage relocation, concealed plumbing, tiling complexity, waterproofing, fixture tier, access constraints and ventilation upgrades are the main cost drivers.

These technical items explain why small bathrooms remain relatively expensive per m².

Summary

Typical 2026 renovation ranges in Ireland:

Ensuite: €7,000–€16,000
