Choosing the right bathtub involves understanding various sizes, types, materials, and features to ensure it fits your bathroom space and meets your preferences.
Considerations Before Buying a New Bathtub
- Bathroom Size and Layout: Measure your bathroom to determine the ideal bathtub size and placement. For smaller spaces, alcove bathtubs or corner bathtubs are space-efficient. Larger bathrooms can accommodate freestanding or drop-in tubs.
- Intended Use: Consider who will use the bathtub and how often. A durable and spacious tub is ideal for families with children. Soaking or whirlpool tubs offer enhanced comfort for relaxation seekers.
- Comfort vs. Size: Ensure the tub is long enough to stretch out, wide enough for comfort, and deep enough for soaking. Standard tubs are 14-16 inches deep, while soaking tubs can be 18-22 inches deep.
- Installation Process: Different tubs have varying installation requirements. Freestanding tubs offer flexibility in placement, while drop-in and corner tubs may require more extensive carpentry or plumbing work.
