Parking and Steps , Bathroom Ceramic Tile Installation

I need my bathroom retiled with medium-format ceramic tiles (anywhere in the 8×8 in to 12×12 in range). The walls and floor are currently finished with dated material that has to be removed and disposed of before laying the new tiles, applying grout, and sealing everything for a waterproof finish... (Budget: ₹1500 - ₹12500 INR, Jobs: Demolition, Flooring, Tiling)
