For your 1999 Fleetwood Southwind 36T shower renovation, a 24” x 32” center drain RV shower pan is recommended based on your measurements and drain location. Along with the shower pan, consider an RV shower surround kit and an RV shower drain assembly or strainer kit to complete the setup. Before ordering, confirm your shower's overall footprint, the exact distance from the drain center to the walls, and door clearance to ensure proper fitment. We’re available to help verify these measurements and make sure you get the right parts the first time. Use code ALIRVP at checkout for a $5 discount on your order.
