How Does Bathtub Size Impact Remodel Costs?

Material Costs

The size of your bathtub directly influences the cost of materials. Larger tubs require more materials, whether it's for the tub itself or the surrounding tiling and fixtures.

For example, a small alcove tub may be less expensive than a large freestanding or whirlpool tub, not just because of the bathtub size but also because of the materials used. High-end materials like cast iron or natural stone will further increase the cost.

Installation Costs

Larger bathtubs often come with higher installation costs due to the complexity of fitting them into your bathroom. Freestanding and drop-in tubs may require more extensive plumbing work or structural modifications to your bathroom floor to support the added weight.

Additionally, the labor required to install a larger tub can be more intensive, leading to higher installation fees.

Additional Plumbing Costs

Depending on the size and type of tub you choose, you may also need to upgrade your plumbing system. Larger tubs, especially whirlpool or soaking tubs, often require more water, which might mean upgrading your water heater or installing additional plumbing lines. These changes can add significantly to your remodeling costs.

How to Choose the Best Bathtub Size

Consider Your Bathroom Space

Your bathroom's size is the first factor to consider when choosing a bathtub. Measure your space carefully to ensure the tub you choose will fit comfortably. A larger tub in a small bathroom can make the space feel cramped, while a small tub in a large bathroom might look out of place. Balancing the size of the tub with the size of the bathroom is key to a harmonious design.

Think About Usage Needs

Consider how the bathtub will be used. If you have a family with young children, a standard alcove tub may be the best choice for practical reasons. However, if you're looking for a spa-like experience, a larger soaking or whirlpool tub might be more appropriate. For couples, a two-person tub could be a luxurious option that adds a romantic element to your bathroom.

Factor in the Style of the Bathtub

The style of the bathtub should complement your bathroom's overall design. Freestanding tubs make a bold statement and work well in larger bathrooms, while alcove and drop-in tubs offer a more seamless look for smaller spaces. The style you choose will also affect the size, as some types of tubs, like freestanding or corner tubs, tend to be larger and require more space.

Budget Considerations

Your budget will play a significant role in determining the size of the bathtub you choose. Larger tubs and those made from premium materials will generally cost more. It's important to balance your desires with your budget, keeping in mind the total cost, including materials, installation, and any necessary plumbing upgrades. Remember that a well-chosen bathtub is an investment that can add value to your home.
