Video Overview

This tutorial demonstrates a retrofit method for adding a floating corner shower shelf to an already tiled wall. Instead of drilling through the tile and waterproof membrane, two small sections of grout are removed on both corner walls to allow the shelf tabs to insert securely. The process focuses on accurate grout removal, dry fitting, and silicone sealing.

Step-by-Step Installation

Step 1 – Determine Shelf Height

Select a shelf height that aligns with the horizontal grout lines and is readily accessible in the shower area.

Step 2 – Mark Install Location

Mark grout joints where installation tabs will insert.

Step 3 – Grout Removal

Remove grout at marked points to create notches, being careful not to chip adjacent tiles.

Step 4 – Clean Notches and Dry Fit

Clean debris and dry fit the shelf to confirm alignment and tab engagement.

Step 5 – Seal and Install Shelf

Apply silicone sealant, insert the shelf, and clean excess for a clean finish.
