Note: This is easiest to do in Play The Sims mode. Get a fire place, then buy a rug and place it under the fireplace. Guy the heart shaped spa. Light the fireplace, get in the spa, and wait until there is a fire. Before your Sim gets out and starts jumping around because of the fire, cancel everything but the spa. Wait until the spa burns up. If done correctly, your Sim will appear in another part of room close to the wall, and will not have their clothes on. Note: The censor will still appear.
