The average cost for Bath Fitter installation runs from $2,000 to $7,000, as of 2015. The exact cost depends on the Bath Fitter product chosen, the features desired by the homeowner and the existing setup in the homeowner’s bathroom.
The cost of the project also depends on the materials selected for the installation. For instance, high-end products and materials cost more than lower-grade materials. Larger bathrooms also cost more than smaller ones. Any add-on items that the homeowner chooses to include in the installation, such as the installation of shelves, towel bars, faucets and other extras, also add to the total cost.
