About BathCozy

What BathCozy Is

BathCozy is an independent, advertising-supported website built around one room: the bathroom. It covers bath rituals and self-care, bathroom design and renovation, and the practical numbers that come with both — how much water a shower uses, what size curtain fits an opening, how much paint, tile, and grout a job needs, and what a renovation is likely to cost. Everything here, from the calculators to the articles, is free to use and paid for by on-page advertising rather than subscriptions or sponsored placements.

What BathCozy Isn’t

BathCozy is not a plumbing, contracting, or design firm, and nobody involved is a licensed plumber, contractor, or interior designer. The site is not affiliated with any tile, paint, or fixture brand, and it doesn’t follow any single building code or manufacturer’s spec — codes and product lines vary by region and change over time. Every calculator here produces a planning estimate, not a professional measurement or quote: results depend entirely on the numbers you enter, and real rooms, materials, and local prices vary. Nothing on this site is professional plumbing, contracting, construction, or health advice — for anything structural, load-bearing, or involving gas or electrical work, check with a licensed professional before you buy materials or start a job.

The Tools

The core of the site is six calculators, each built around a single real question:

• Bathroom Water Usage Calculator — add up showers, baths, the toilet, and faucets to see gallons used per day, month, and year, the estimated cost, and which fixture is the biggest draw.
• Shower Curtain Size Calculator — enter your opening width and curtain type to get a curtain and liner size, ring count, and rod width matched to standard off-the-shelf sizes.
• Bathroom Paint Calculator — turn room dimensions, coats, doors, and windows into paintable area and the gallons to buy, with standard deductions and a note on moisture-resistant finish for steamy rooms.
• Grout Calculator — enter area, tile size, thickness, and joint width to get pounds of grout and the number of 25-pound bags, using the standard tile-industry coverage formula.
• Bathroom Tile Calculator — work out the tiles and boxes needed for a floor or wall from area, tile size, and a waste allowance.
• Bathroom Renovation Cost Calculator — choose a size and quality tier, add scope items like a new tub, vanity, or plumbing move, and see a low-to-high cost range with a line-item breakdown.

Each one runs on a published formula or a widely used industry coverage figure — the tile-industry grout-coverage formula, standard paint-coverage rates, typical fixture flow rates for water use — rather than a guess. They’re meant as a starting point for planning a bathroom project, not a substitute for measuring the actual room or getting a contractor’s quote.

Guides and the Museum

Alongside the calculators, the blog and learn section cover bath rituals, bathroom design, and renovation planning in more depth. For anyone curious about the history behind the room, the Museum of Bath & Bathingis a separate, browsable collection covering the great bathing places of the world, the ritual of the soak, the fixtures of the modern bathroom, and the wellness of the spa and hot spring — every entry, image, and fact is drawn from Wikipedia and Wikimedia Commons.

Independence

BathCozy is not affiliated with any bathroom brand, standard, or governing body it mentions, and doesn’t accept payment to feature a product or method in a calculator. The site runs on display advertising, which is why you’ll see ads alongside the tools and articles. Questions, corrections, or tool suggestions are welcome — see Contact.
