How to Choose the Right Shower Size
Choosing the right shower size depends on several important factors.
1. Measure Your Bathroom
Always measure the available floor space before purchasing a shower enclosure. Leave enough room for doors, fixtures, and comfortable movement.
2. Consider Daily Use
A guest bathroom may only require a compact shower, while a master bathroom benefits from a larger enclosure for added comfort.
3. Think About Future Needs
If you plan to stay in your home for many years, choosing a larger or more accessible shower can improve long-term convenience.
4. Match Your Budget
Larger showers require more tile, glass, plumbing, and labor. Balance your desired features with your renovation budget.
Common Shower Size Mistakes
Avoid these common mistakes when planning your shower:
- Choosing a shower that’s too small for everyday comfort.
- Ignoring the space needed for shower doors.
- Forgetting to account for plumbing locations.
- Not planning storage niches or shelves.
- Selecting style over functionality.
- Failing to measure accurately before ordering.
Proper planning helps prevent costly remodeling mistakes.
