Big box epoxy kits are a real product, and for a small, dry, low stakes floor a quality kit applied patiently can look good and hold up. Bathrooms are where the gap opens up. Surface prep is the failure point in almost every bad epoxy floor: acid etching from a bottle does not open a slab the way diamond grinding does, and coating over an unopened slab peels. A kit also gives you no way to test whether moisture will lift the floor next spring, ships a thinner film than professional systems, and cannot easily cove up the wall or cut in cleanly around a toilet. And a wet bathroom needs an anti slip additive dialed to the room, not a generic amount. One seasonal bonus: epoxy cures slower in the cold, but an interior bathroom in a heated house is workable year round, which makes it a strong winter project here while exterior slabs wait for spring.
