Shower Base Support Reinforcement

I am doing a job for a veteran. Overweight, possibile wheel chair in future. Point loads for this man in a wheelchair are high; a concrete shower base has been suggested. Improved support is required for the floor base.

Requirements

- Add reinforcement brackets to the existing shower base. - Current base is tiled, so the solution must be compatible with tile. - Brackets should be made of stainless steel. Ideal Skills and Experience: - Experience working with tile and shower bases. - Knowledge of structural reinforcement techniques. - Proficiency in working with stainless steel.
