tub car sim [2X EXP]
A Roblox experience owned by Developing with friends.
Description (written by the developer; not a statement by this register)
Welcome to the wildest bathroom-based racing adventure on Roblox, where speed meets soap and every bathtub becomes a turbocharged machine of chaos! In Tub Car Simulator, players jump into customizable bathtub cars and race through hilarious obstacle courses, slippery highways, giant bathrooms, foam-filled arenas, and outrageous stunt maps designed to test both skill and sanity. Start with a rusty little tub that barely squeaks across the tiles, then train, upgrade, and unlock insane engines powerful enough to launch your bathtub into orbit. Collect coins, boosts, rubber ducks, bubbles, and rare upgrades as you speed through loops, ramps, waterfalls, sewer tunnels, and giant household environments where even the toothpaste can become a deadly obstacle.
