Bath and Shower Separation
Many bathrooms use a bath/shower combination that give you an option when it comes time to get clean and it also saves space. However, if you and your partner are both trying to get ready for work in the morning, it can cause problems. You may have to wait while your spouse gets finished in the shower until you can take your own in order to get ready for work.
If you bathroom size allows it, separate the bath and shower so they each have their own space and they can be used independently. This will allow you both to use the bathroom at the same time in order to get ready for work. It also works ideally if one of you would rather shower and the other would rather bathe.
