cost to reseal a bathWhat does it involve to reseal a bath?

As we mentioned before, it’s pretty straightforward to reseal a bath. Here’s a quick step-by-step rundown of the process:

  1. The plumber will remove all the old sealant.
  2. They’ll fill the bath with water (which will affect where the edge of the bath sits).
  3. The new sealant is added and left to dry.
  4. The bath is emptied once the sealant is dry.

The whole process of resealing a bath takes between 60-90 minutes.

Factors affecting the cost resealing a bath

There are a number of factors that can affect the price to reseal your bath, including:

  • Size of bath
  • Condition of old sealant
  • Type and quality of new sealant
  • The time it takes to do the job
  • Any prep work needed
  • Where you live

Why do I need to reseal a bath?

Resealing your bath is important for a number of reasons. Firstly, it ensures that your bath has a water-tight seal along the wall, which protects it from leaking and water overflowing the edge of the bath. Leaks or water seeping down the side of your bathtub can lead to mould and rot.

If left unnoticed, water leaking from your bath can affect neighbouring rooms in your home, and even neighbouring properties. For the small cost to reseal your bath you can avoid expensive repair work down the line.

In addition to the practical benefits, resealing your bath also spruces it up and gives it a fresh look at a very affordable price.

Useful bath resealing checklist

  • Check the condition of your existing bath sealant, if it looks damaged or there is water seeping through then it’s time to reseal your bath.
  • Speak to local plumbers for their professional advice and accurate quotes.
  • Shop around for fair and competitive costs to reseal a bath.
  • Always hire a tradesperson with relevant experience.
