You can buy a simple two-piece toilet that comes with a wax seal and toilet bolts for as little as $150 to $200. Or you can purchase a higher comfort toilet that comes with everything from $250 to $400. One-piece toilets start at around $250 and can go up to $1000. Water-saving toilets start at around $250 and could go up to $400. Some toilets will come with wax seals and toilet seats, and some do not come with these parts included, so it’s important to consider these costs if your toilet is not a complete package.
