Bathroom planning / Adding a room

Adding an ensuite: what to plan

Adding an ensuite is more than fitting a shower into spare floor area. The new room needs to work with the bedroom, services and the rest of the home. Test the space and approval questions before committing to fittings or a final layout.

Compare a new room with improving the existing bathroom

Write the problem you want to solve: morning congestion, privacy or easier access from a bedroom. Then consider whether a new ensuite is the best way to meet it, or whether a change to the existing bathroom deserves comparison. Fix All’s bathroom and renovation services provide a route to discussing the building work involved.

Building workWhat walls, floors and finishes will be affected?Photos and a list of features to keep.
ApprovalsAre sanitary fixtures being added to the building?Existing and proposed fixture counts and the full scope.

Prepare an ensuite enquiry

  1. Explain why an additional bathroom is needed.
  2. Sketch the proposed position and the adjoining rooms.
  3. Show where the existing bathroom and other wet areas are.
  4. List whether shower, basin and toilet are all proposed.
  5. Bring any drawings, reports or council advice already obtained.

Borrowing wardrobe space has a second effect

Using part of a bedroom wardrobe might create room for an ensuite, but the household still needs somewhere to store clothes. Compare the finished bedroom as well as the new bathroom. Include replacement storage in the overall scope rather than leaving it as an extra later.

Is adding an ensuite the same as moving existing fixtures?

No. MBIE’s plumbing guidance gives an added ensuite with additional shower, basin and toilet fixtures as an example needing building consent. That differs from qualifying alterations to existing fixtures. Confirm the complete project with the relevant professionals and council before work begins.
