- Plumbing distance
- Tying into nearby supply and drain lines is cheap; running new lines across the house — or adding a stack — adds thousands.

- New plumbing and electrical trigger permits and inspections; venting and code compliance are non-negotiable line items.

How to read these Ireland figures. The cost is the US national midrange benchmark adjusted by a Dublin, IE cost multiplier (1.08×) and shown in EUR. The “% recouped at resale” is a national (US-derived) Cost-vs-Value benchmark applied to the local cost — it is not a locally measured resale figure, and real recovery varies by Ireland market conditions.
