Bilal Mansuri/Unsplash Living in an apartment in New York City with a 10×10 bathroom is a luxury in today's era, when most others feature a smaller footprint. It's a generous size, which also means you will spend more on renovations. Are you planning to upgrade it? Typically, this size of bathroom renovation project costs anywhere between $8,000 and $60,000. A low-budget bathroom can be completed for $8,000 to $15,000, while a mid-range upgrade can be expected to cost $15,000 to $30,000. Of course, anything above this falls under the luxury category.
