Why bathroom renovation costs vary in Ireland (2026), including specification differences, labour scope, VAT treatment and structural cost drivers.
1. Overview
Bathroom renovation quotes in Ireland commonly vary by:
10% – 40%
Even when pricing what appears to be the same room.
This variation typically results from differences in:
- Specification level
- Fixture allowances
- Waterproofing scope
- Plumbing assumptions
- Labour structure
- VAT inclusion
- Risk pricing
Headline price alone rarely reflects true scope.
2. Specification Differences
The largest cost variation factor is fixture specification.
Example comparison:
| Item | Budget Allowance | Mid-Range | Premium |
|---|---|---|---|
| Toilet | €300 | €1,200 | €2,500 |
| Vanity | €700 | €1,500 | €4,000 |
| Shower system | €250 | €800 | €2,500 |
| Bath | €400 | €1,800 | €4,500 |
| Fixture Total | €1,650 | €5,300 | €13,500 |
Specification alone can create €10,000+ variation.
3. Tiling Scope Differences
One quote may assume:
- Half-height wall tiling
Another may assume:
- Full-height tiling on all walls
Example:
| Scope | Approx Tiled Area | Installed Cost (@€110/m²) |
|---|---|---|
| Half-height walls | 18m² | €1,980 |
| Full-height walls | 35m² | €3,850 |
Difference: €1,870
Tile selection multiplies this variation.
4. Plumbing Assumptions
Quotes may differ based on:
- Layout retention assumption
- Drainage relocation allowance
- Soil pipe modification inclusion
Example:
| Plumbing Scenario | Cost |
|---|---|
| Layout retained | €2,000 |
| Toilet relocation included | €4,500 |
| Drainage alteration included | €7,000+ |
If one contractor includes relocation and another excludes it, quotes diverge sharply.
5. Waterproofing Scope Differences
Some quotes include:
- Shower-only tanking
Others include:
- Full-room tanking
Example:
| Waterproofing Scope | Cost |
|---|---|
| Shower-only | €1,200 |
| Full wet-zone | €2,000 |
| Full-room | €3,500 |
Difference may exceed €2,000.
6. Labour Structure
Contractors price labour differently:
- Fixed-price project
- Day-rate basis
- Subcontracted trades
- In-house team
Labour risk pricing varies based on:
- Experience
- Programme certainty
- Project complexity
Two identical scopes may vary by €2,000–€5,000 based on labour model.
7. VAT Treatment
One quote may be:
- Inclusive of VAT (13.5%)
Another may be:
- Exclusive of VAT
On a €15,000 construction cost:
13.5% VAT = €2,025
Failure to confirm VAT inclusion can distort comparison significantly.
8. Access and Site Constraints
Bathrooms located:
- On upper floors
- In older properties
- With restricted access
may incur additional labour.
Upper-floor installations typically cost 10–20% more.
9. Hidden Conditions
Cost variation often arises from unknown factors:
- Uneven floors
- Rotten timber
- Poor ventilation
- Inadequate drainage fall
- Electrical board capacity
If one contractor includes risk allowance and another does not, price differs.
10. Quote Structure Differences
Some quotes include:
- Fixtures supply
- Tiling supply
- Waste removal
- Project management
Others exclude these.
Example:
| Item | Contractor A | Contractor B |
|---|---|---|
| Fixtures | Included | Excluded |
| Tiling supply | Included | Excluded |
| Waste removal | Included | Excluded |
| VAT | Included | Excluded |
| Headline Price | €18,000 | €14,500 |
Scope alignment may equalise totals.
11. Typical Variation Ranges
| Project Type | Normal Variation |
|---|---|
| Basic ensuite | 10–20% |
| Mid-range bathroom | 15–25% |
| Wet room | 20–40% |
Higher complexity increases variation range.
12. Example Scenario Comparison
Quote A
- Construction: €14,000
- VAT included
- Fixtures mid-range
- Full waterproofing
- Layout retained
Quote B
- Construction: €12,000
- VAT excluded
- Fixtures allowance €2,000
- Shower-only tanking
- Layout relocation excluded
After adjusting scope:
Quote B may exceed €17,000.
Headline comparison alone is misleading.
13. Regional Cost Variation (Ireland)
Costs may vary slightly based on:
- Dublin and commuter belt pricing
- Labour demand
- Contractor availability
Regional variation typically ranges:
5% – 15%
Specification remains dominant factor.
14. Summary
Bathroom renovation costs vary in Ireland due to:
- Specification level
- Tiling scope
- Plumbing assumptions
- Waterproofing coverage
- Labour structure
- VAT treatment
- Hidden conditions
Headline price is not a reliable indicator without detailed scope comparison.
