5 top-rated tub-to-shower pros near Portsmouth

Before you convert, ask this

  1. Will the new shower keep the existing drain location, or does the drain move?
  2. Is this a standard base, a low-threshold pan, or a full curbless build, and what does the subfloor work look like for each?
  3. Will there be a grab bar blocking installed inside the walls, even if a bar isn't mounted on day one?
  4. What valve type is going in, pressure-balance or thermostatic, and what brand?
  5. Who handles the waterproofing before tile or panels go up, and what product do they use?
  6. Is there another tub left in the house, or does this conversion remove the last one?
  7. How many days will the bathroom be unusable?
