The basic or standard tub that does not include any additional features and is of fiberglass or acrylic starts at $200 to $300. You can spend little with that price range as your starting point. If you like an air bathtub or whirlpool tub, then you are looking at $700 to $900 a piece, which is at the lower end. It can cost more than $1,500 for combination.
Bathtubs that have unusual sizes and shapes, whether to fit in a unique bathroom configuration or for comfort, most likely cost more than the standard bathtubs. Those that are high in quality or made of aesthetic materials like stone and copper can be pretty expensive as well.
It is important that you keep in mind a tub’s cost is not the final cost. The installation of the bathtub may be too complicated for you to do unsupervised by a professional. Unless you are an expert yourself, you will need to consult and hire one.
There are kinds of bathtubs that require more during the installation process compared to others, particularly the undermount and drop in bathtubs. If you are replacing an existing one or you are doing a remodeling, selecting a different place in the bathroom and/or a different type and size of tub will increase the installation costs.
If you choose a deeper tub than what you had before, then you will find yourself needing to purchase a water heater. Be prepared for this extra cost. Any tubs with new technology like whirlpools and air tubs would require more ongoing maintenance. Not to mention, future repairs.
Working out the entire cost of a bathtub is complicated and it is worth talking to an expert for advice and assistance on every aspect. Do so before you make a purchase, so you have an idea on the cost of your new bathroom addition.
