Primary Bathroom Remodel design

The one bathroom with room to make choices instead of compromises.

What the room has to do

A primary bathroom has the square footage to separate the wet zone from the dressing zone, which is the whole difference between it and a family bath. The remodel is usually about earning that separation: a bigger shower, a double vanity, and somewhere to stand that is not in front of the toilet.

Layout rules

  • A double vanity needs 60in minimum; at 72in the two basins stop competing for the same elbow room.
  • A walk-in shower without a door wants 42in of wet-zone depth so spray does not reach the room.
  • Leave 30in in front of a freestanding tub on its access side, 6in behind for cleaning.
  • A shower bench is 17–19in high and at least 15in deep to be worth building.
  • Separate the toilet with a 32in partition or a door if the room is over 80 sq ft.

Lighting plan

Two circuits at least: a bright dressing layer over the vanities and a low warm layer for the tub and shower. Put the low layer on its own switch — the point of a primary bath is being able to use it at 6am without the full array on.

What usually goes wrong

  • A vast shower with a single ceiling head, so it is cold everywhere except directly underneath.
  • A tub installed where nobody can reach around it to clean.
  • Two basins crammed into 48in, which is one basin with extra plumbing.
  • Glossy floor tile in the wet zone.

In a small one

If the room will not take a tub and a real shower, drop the tub. A generous shower used daily beats a tub used twice a year, and the space it frees is what makes the rest of the room work.
