A small bathroom, typically 5 by 8 feet or 6 by 6 feet, does best with a few specific moves: keep plumbing fixtures in their existing spots, add storage vertically instead of on the floor, and consider replacing a tub with a walk-in shower to gain usable space. A cosmetic refresh runs $3,000 to $8,000, and a fuller remodel with new tile and fixtures runs $8,000 to $18,000 or more.
Small does not have to mean cramped. Small bathroom remodel projects have a specific set of moves that work reliably, and they are different from what works in a larger primary bathroom. According to This Old House, small bathrooms typically measure 5 by 8 feet or 6 by 6 feet, just enough room for a toilet, sink, and a combination shower and tub or a standalone shower.
A large share of the Massachusetts homes we work in, especially triple-deckers around Worcester and older colonials in Framingham and Marlborough, were built with exactly this size bathroom. Here is what actually works in that footprint, and what does not.
What Counts as a Small Bathroom
This Old House's cost data breaks small bathrooms down by square footage, and the price climbs quickly even within the "small" category: a 5 by 6 foot bathroom (30 square feet) runs $11,900 to $15,100 for a full remodel, while a 6 by 8 foot bathroom (48 square feet) runs $19,000 to $24,100. The lesson is that even an extra few square feet moves the budget meaningfully, so knowing your exact dimensions before you plan matters more in a small bathroom than a large one.
Layout Tricks That Actually Free Up Space
The single biggest layout mistake in a small bathroom remodel is moving plumbing fixtures for the sake of a "better" layout. This Old House specifically recommends keeping plumbing fixtures like the toilet, sink, and bathtub in their original locations, since relocating them adds the cost of rerouting supply and drain lines on top of everything else.
Within that constraint, a few moves make a real difference. Bob Vila's small bathroom guide points to corner sinks as a way to open up a tight floor plan, since a corner sink frees the wall space a standard vanity would otherwise block. Leaving at least 30 inches of clearance in front of any fixture also keeps the room from feeling like a hallway.
Storage Ideas That Do Not Eat Floor Space
Bob Vila's space-saving strategies for small bathrooms center on one idea: put storage on the walls and ceiling instead of the floor. A mirrored medicine cabinet adds storage and light at the same time. Recessed shelving built between the wall studs adds a few inches of storage depth without stealing any floor space at all, which matters in a room where every square foot is already accounted for.
Swapping a hinged bathroom door for a pocket or sliding barn door removes the swing radius the door needs, which can be the difference between a vanity that fits and one that does not.
Fitting a Walk-In Shower in a Small Footprint
Removing a tub you rarely use is often the single biggest space win available in a small bathroom. A code-minimum shower is only 30 by 30 inches, and a comfortable one runs 36 by 36 inches or larger, both smaller than the footprint most tubs occupy. See our shower sizes and dimensions guide for the exact numbers, and our bathtub materials guide if you are still weighing whether to keep a tub at all.

This Old House's component cost data shows tiling runs about $33 per square foot compared to $13 per square foot for painting, which is exactly why a small accent of upscale tile, a shower niche, a single feature wall, reads as a bigger upgrade than tiling the entire room in the same premium material. Spend on the shower and the tile you touch every day; save on paint, hardware, and anything outside the wet area.
What a Small Bathroom Remodel Costs
This Old House puts a small bathroom cosmetic refresh at $3,000 to $8,000 and a mid-range update at $8,000 to $18,000, with premium renovations running $18,000 and up. Our own bathroom remodeling pricing for a small tub-to-shower conversion in Central Massachusetts, keeping the existing footprint, typically lands at $4,000 to $8,000, in line with that national data. See our full bathroom remodel cost breakdown for how pricing scales with project size.
The Bottom Line
A small bathroom does best when you keep the plumbing where it is, push storage onto the walls instead of the floor, and consider trading an unused tub for a walk-in shower. Spend on the shower and the tile you see every day, and save everywhere else. Get a contractor to measure your exact space before you commit to a layout on paper. Get a Free Bathroom Estimate
FAQ
What is considered a small bathroom?
Most small bathrooms measure 5 by 8 feet or 6 by 6 feet, just enough room for a toilet, sink, and a combination shower and tub or a standalone shower, according to This Old House. Many older Massachusetts homes, especially triple-deckers and pre-1950s colonials, fall into this size range.
How much does a small bathroom remodel cost?
A cosmetic refresh of a small bathroom typically runs $3,000 to $8,000, while a fuller remodel with new tile, vanity, and fixtures runs $8,000 to $18,000 or more depending on materials. In Massachusetts, a small tub-to-shower conversion in the same footprint usually runs $4,000 to $8,000.
Can you fit a walk-in shower in a small bathroom?
Yes, in most cases. A 30 by 30 inch shower is the minimum legal size under code, and a 32 by 32 or 36 by 36 inch shower fits comfortably in most small bathrooms once the tub is removed, often freeing up more usable floor space than the tub took.
