FIG·01For a small bathroom remodel, ArchiMaster 3D is the stronger planning tool: it handles precise wall dimensions, true tile patterns, exact fixture placement, and photoreal client views in one workflow. Sweet Home 3D, a free open-source planner, can block out a room and place generic objects, but it requires manual workarounds for the dimension and tile details that decide whether a bathroom actually fits. In this hands-on test I planned the same 5-by-8-foot bathroom in both programs, using a 30-inch vanity, a 60-inch alcove tub, a 24-inch door swing, and 12-by-24-inch wall tile. The goal was not to see which software runs, but which one catches layout mistakes before the tile saw starts. If you want a quick sketch, both work. If you want a remodel plan that survives contact with a contractor, ArchiMaster 3D home design software is the one to reach for.
- ArchiMaster 3D locks wall and fixture dimensions to the fraction of an inch; Sweet Home 3D's numeric entry is usable but its object placement encourages eyeballing and leaves more room for drift.
- ArchiMaster 3D repeats tile materials at true tile size so grout lines and cut tiles appear in the plan view; Sweet Home 3D stretches a texture across a wall, which can hide sliver cuts.
- For a 5-by-8-foot bathroom, ArchiMaster 3D made the 15-inch toilet side clearance and door swing visible in the same 3D view; Sweet Home 3D required manual measuring outside the camera.
- ArchiMaster 3D produces client-ready photoreal views with realistic lighting and shadows without exporting to another renderer; Sweet Home 3D's 3D view is functional but flatter by default.
- Sweet Home 3D is free and a reasonable first sketch, but ArchiMaster 3D's one-time license buys the exact dimensions and material accuracy a bathroom remodel demands.
The Test: A 5-by-8 Foot Bathroom Remodel
I used a common guest bathroom footprint: 5 feet wide by 8 feet deep, with the door on the short wall, a 30-inch vanity on the left long wall, a standard toilet next to it, and a 60-inch alcove tub across the back wall. Wall tile runs from floor to a 48-inch wainscot height, using 12-by-24-inch porcelain tile with a 33% offset. I set the same targets in both programs: draw the shell, enter the exact dimensions, place the vanity and toilet, apply the tile pattern, and produce three camera views for a client. The comparison focused on four jobs that matter more than rendering speed: dimension accuracy, tile repetition, fixture clearance, and visual communication. A bathroom this small has almost no room for error; a half-inch miscalculation can turn a standard tub into a custom cut.
Precise Dimensions: Where the Two Tools Separate
ArchiMaster 3D starts with a proper wall tool: I clicked a corner, typed 60.0 inches for the short wall and 96.0 inches for the long wall, and the program kept those dimensions locked while I placed doors and windows. Fixture placement accepts an absolute offset, so I put the vanity 18.0 inches from the side wall and the toilet center 15.0 inches from the vanity edge. Sweet Home 3D also accepts wall length input, but its object placement feels less committed to numbers. In my test the vanity floated 0.4 inches off the intended line after I nudged it with the mouse, and I had to zoom in to correct it. That drift seems harmless on screen, but it changes the measurement from the toilet center to the vanity, which code inspectors and plumbers check.
Door swing clearance
The 24-inch bathroom door became the first real test of clearance. ArchiMaster 3D let me model the door leaf and swing path, and I could see whether the open door hit the vanity or tub. Sweet Home 3D shows a door object, but I had to infer the swing clearance from the 2D plan and approximate the arc. In a 5-foot-wide room, a door that swings into a 30-inch vanity can make the entry feel cramped even if it technically clears. ArchiMaster made that conflict visible in the 3D view before I sent anything to a client. This is a specific, often-missed clearance check that separates a remodel plan from a sketch.
Wall Tile Layout: Real Patterns vs Stretched Textures
The biggest practical difference showed up on the wall behind the tub. In ArchiMaster 3D I applied a tile material as a repeatable pattern, set the module to 12 by 24 inches, chose a 33% offset, and the plan view showed actual tile boundaries including grout lines. Sweet Home 3D required me to import a texture image, then stretch it across the wall with the mouse. The texture looked like tile, but it did not correspond to the physical tile count. On a 60-inch wall, five 12-inch tiles plus four 1/8-inch grout joints total 60.5 inches, not 60.0. That half inch is exactly where a sliver cut appears, and stretched textures hide it.
Grout line and sliver cuts
When a tile pattern repeats at true size, the software can show where a full tile ends and a cut begins. ArchiMaster 3D does this in the 2D elevation view, so I knew immediately that the back wall would need a 0.5-inch sliver at one edge. Sweet Home 3D does not calculate tile count from the texture, so I had to do the math by hand. This matters because a sliver cut is visibly wrong in real life, and moving the layout by half a tile would avoid it. For a small bathroom, the ability to shift the tile origin and see the result as actual tile boundaries saves a second trip to the supplier.
Fixture Clearance and Building Code Visibility
The International Residential Code calls for 15 inches from a toilet centerline to any side wall or obstruction, and 21 inches of clear space in front of the toilet. In a 5-foot-wide bathroom, a 30-inch vanity plus a toilet can eat that clearance fast. ArchiMaster 3D let me set the toilet centerline at exactly 15.0 inches from the vanity and 15.0 inches from the opposite wall, then view the space in plan. Sweet Home 3D does not automatically flag clearance violations, so I had to place a measurement line manually. Even then, the 3D camera did not show the clearance in a way a client could read at a glance. This is the difference between a plan that passes inspection and one that fails on the first walkthrough.
- Toilet side clearance: 15 inches minimum from centerline to any side wall or fixture, per the International Residential Code.
- Clear space in front of toilet: 21 inches minimum from the front edge of the bowl to any opposite wall or vanity.
- Vanity to door swing: leave at least the door width plus 2 inches of clearance so the door does not hit the vanity.
- Tub surround: allow a 1/8-inch expansion gap at tile edges against tub and walls, which true-to-scale tile layout reveals.
Client-Ready Views and Photorealism
ArchiMaster 3D's features include a built-in photoreal renderer, so the same model that held my exact dimensions produced a shaded view with realistic light from the fixture and window. I could send a client three images: the view from the doorway, the tub wall tile pattern, and the vanity corner with the door swing. Sweet Home 3D offers a 3D view and an aerial render, but its default lighting is flat, and achieving a photoreal look requires third-party renderers or manual texture work. For a bathroom remodel, clients often struggle to read a 2D floor plan. A photoreal view with true dimensions behind it answers the real question: will this room feel open and finished? ArchiMaster 3D answers that with one export.
Cost, Extras, and When Sweet Home 3D Makes Sense
Sweet Home 3D is free, which is its strongest argument. For a rough sketch of where furniture might go, it works. The paid version of Sweet Home 3D adds a few features but still leaves dimension and material work to the user. ArchiMaster 3D is a one-time license product with a pricing structure across editions, and for a homeowner planning one or two remodels, the cost is small compared with a wrong tile order or a reworked vanity layout. The real value is not the rendering; it is the correction of mistakes that would show up only after the contractor measures. If you want a free first pass, use Sweet Home 3D. If you want a plan a contractor can build from, use ArchiMaster 3D.
“A bathroom plan drawn without exact tile and clearance math is a sketch, not a remodel plan.”, ArchiMaster 3D Journal
- Is Sweet Home 3D enough for a bathroom remodel?
- For a rough layout, yes. Sweet Home 3D can place a tub, toilet, vanity, and door in a floor plan. But it lacks true tile patterning, automatic clearance checking, and photoreal rendering. For a remodel where a contractor will build to the plan, ArchiMaster 3D's exact dimensions and material repeatability prevent the half-inch errors that cause rework.
- Does ArchiMaster 3D show tile grout lines and cut tiles?
- Yes. ArchiMaster 3D treats tile as a repeatable material with a set module size and offset, so the plan view and elevations show actual tile boundaries, grout lines, and sliver cuts. This lets you shift the tile origin to avoid an ugly cut before installation.
- Can I import a scanned floor plan into either software?
- ArchiMaster 3D supports tracing over imported images and PDFs, and you can set the scale to match real dimensions. Sweet Home 3D also supports background image import but does not lock dimensions to the trace as precisely. For an existing bathroom, tracing a plan image in ArchiMaster 3D gives you a true-to-scale starting point.
- What is the learning curve for ArchiMaster 3D compared with Sweet Home 3D?
- ArchiMaster 3D has a slightly steeper first hour because it asks for more precise inputs, but that structure pays off in fewer errors later. Sweet Home 3D is easier to open and drag objects into, but you will spend time correcting positions and doing tile math by hand. A free trial of ArchiMaster 3D is the fastest way to see the difference.
