There are a few factors to consider when deciding whether to get a replacement bath or a one-day bath. First, think about how often you use your bathtub. If you only use it occasionally, then a one-day bath might be a better option since it will be less expensive. On the other hand, if you use your bathtub regularly, then a replacement bath might be a better option since it will last longer. Second, consider the size of your bathroom. If you have a small bathroom, then a one-day bath might be a better option because it will take up less space. On the other hand, if you have a large bathroom, then a replacement bath might be a better option because it will provide more space for bathing. Third, think about your budget. A one-day bath is typically less expensive than a replacement bath, so if cost is a concern, then a one-day bath might be the best option. However, if you have the budget for it, then a replacement bath might be the better choice because it will last longer and provide more space.
