Designer Tips for Bathroom Budgets

• Waterproofing done right, not twice. This is the one place never to economize — a leak costs 10x the saving.
• Keep the plumbing footprint. Moving a toilet or shower drain is the fastest way to blow the budget.
• Large-format tile = fewer grout lines = easier cleaning and a more luxurious look.
• Layer the lighting: sconces at the mirror (no overhead shadows), dimmable ambient, and a night light path.
• Know the scope. For background on what bathroom renovations typically involve, see Wikipedia’s renovation article.
