Simple Project bathroom bundles compared: Golden Tranquility vs Urban Stillness, pump power (750W/600W/500W), MT‑1 vs MT‑4, and door sizes

What actually differs across these Simple Project bathroom bundles

Both lines center on the same core idea: a coordinated vanity/cabinet set with an upflush (macerating) toilet and a matching shower door. The key differences are aesthetic and fit—plus how the toilet and door are configured.

• Finish and vibe: Golden Tranquility leans brushed‑gold + white; Urban Stillness skews matte black or brushed nickel details.
• Shower door type/size: Golden uses a single‑sliding 56–60 in W x 75 in H door. Urban pairs with CALYZ pivot doors at 71 in H, sized to 38–42, 44–48, or 50–54 in openings (about 4 in adjust).
• Toilet format: MT‑1 = two‑piece; MT‑4 = one‑piece. Urban Stillness pages show MT‑1 with a round bowl and MT‑4 with an oblong bowl.
• Medicine cabinet: 36x24 in lighted unit with stepless CCT, quick defogger, motion‑sensing interior light, and built‑in outlets + USB; surface or recess mount; UL‑plugged power.

Pump power: 750W vs 600W vs 500W (match to run length and lift)

Choose the macerator by the longest vertical rise and horizontal run from the toilet to your soil stack, and by how many fixtures share the pump. Manufacturer specs list these approximate capabilities:

• 500W: up to about 23 ft vertical / 230 ft horizontal
• 600W: up to about 29 ft vertical / 295 ft horizontal
• 750W: up to about 36 ft vertical / 360 ft horizontal
• Rules of thumb: pick the smallest pump that still covers your actual path. Go up a class if you’ll have longer pipe runs, steeper lifts, multiple fixtures on the same pump, or many bends. Always verify local code and venting requirements.

Two‑piece MT‑1 vs one‑piece MT‑4 macerating toilets

Both are upflush designs intended to avoid slab cuts. Your choice comes down to installation preferences and the look you want.

• MT‑4 (one‑piece): A streamlined profile with an oblong bowl. Simple Project’s install guide notes the one‑piece can avoid certain floor drilling and extension‑pipe steps, which may simplify DIY.
• MT‑1 (two‑piece): A traditional two‑piece arrangement with a round bowl shown on Urban Stillness. Some buyers prefer the familiar layout for serviceability.
• Noise: The 750W system’s marketing cites about 35–45 dB during operation. Actual sound will vary by room finishes, mounting, and venting. Use proper isolation and alignment to minimize vibration.

Shower door choices: pivot vs sliding and how to size

Urban Stillness bundles pair with CALYZ pivot doors; Golden Tranquility bundles pair with a wider single‑sliding door. Size to your finished opening and pick a finish to match hardware.

• CALYZ pivot doors (Urban Stillness): 71 in height with three width ranges—38–42, 44–48, 50–54 in. ANSI‑certified 1/4 in (6 mm) tempered glass, reversible left/right install, about 4 in of adjustability, and included perimeter/bottom seals. Finishes: matte black or brushed nickel.
• Sliding door (Golden Tranquility): 56–60 in width x 75 in height, single‑sliding format in brushed gold, brushed nickel, or matte black options shown on the bundle page.
• Pivot vs sliding: Pivot works well for narrower or variable openings and easier cleaning access; sliding maximizes entry width on wider openings without a door swing. Measure clearance and splash zones before choosing.

36x24 in lighted medicine cabinet: fit, power, and useful details

The 36x24 unit pairs neatly with 36 in vanities and common stud layouts. It’s designed for convenient plug‑in use and offers flexible mounting.

• Size and mount: About 36 in W x 24 in H x 4.3 in D; surface or recess mount into typical 2x4 walls per manufacturer listing.
• Lighting and clarity: Stepless color‑temperature selection (3000K/4500K/6500K) plus a quick‑acting defogger; motion‑sensing interior light.
• Power and ports: Built‑in outlets + USB with a UL‑certified US plug. A major retailer listing for the Simple Project 36x24 model calls out two 110V/12A outlets and two 5V/2A USB ports. If you want wall‑switch control, check the product page/user manual for supported wiring options and switch logic before purchase.

Warranty, delivery, and returns (what to expect)

Simple Project bundle and door pages commonly show 4–7 day delivery windows, 30‑day free returns, and a 1‑year limited warranty noted for shower doors. SNFLEX macerating toilets list 2‑year ceramic coverage plus 1‑year pump coverage on their collection pages. Confirm the exact warranty and who services each component at checkout.

Answers to common shopper questions

• How far can the macerating toilet pump? Manufacturer specs list about 23/230 ft (500W), 29/295 ft (600W), and 36/360 ft (750W) for vertical/horizontal distances. Size to your path and code needs.
• MT‑1 vs MT‑4—what’s easier to install? Simple Project’s own guidance notes the one‑piece MT‑4 can avoid certain floor drilling/extension‑pipe steps. Choose MT‑4 for a cleaner profile and potentially simpler DIY; MT‑1 for a familiar two‑piece setup.
• Can the 36x24 cabinet recess into a 2x4 wall and plug in? The cabinet is about 4.3 in deep and supports surface or recess mount with a UL‑listed US plug per the product page.
• Can I control the cabinet lights by a wall switch? Check the product page/manual for supported control methods; many users rely on onboard touch controls, but wiring options vary by model and installation.
• Are CALYZ pivot doors reversible and adjustable? Yes—reversible left/right with roughly 4 in of width adjustment, in 38–42, 44–48, and 50–54 in models, all 71 in high.
• Pivot vs sliding—what about splash and cleaning? Pivot doors offer a simpler panel to clean and a defined swing; sliding maximizes passage width on wide openings and avoids door swing. Plan clearances and drip/splash zones accordingly.
• What about noise? Marketing for the 750W system cites about 35–45 dB. Noise depends on mounting and venting—use solid, true plumbing runs and isolation pads to reduce vibration.
• Who handles parts and service? Bundle pages list 4–7 day delivery, 30‑day free returns, and limited warranty terms; SNFLEX toilets note 2‑year ceramic + 1‑year pump coverage. Confirm per component at checkout.

What buyers liked

Across public homeowner and remodeling discussions, positive themes show up repeatedly. These are impressions, not lab measurements:

• Upflush convenience for basement or far‑from‑stack baths—avoiding slab cuts and speeding projects when properly planned and vented (examples: reddit.com/r/Plumbing/comments/1bwiik3, reddit.com/r/HomeImprovement/comments/siem89).
• Pivot‑door flexibility and easier cleaning access vs sliders in smaller openings (examples: reddit.com/r/Remodel/comments/1r13km7, reddit.com/r/Plumbing/comments/ks8fah).
• Lighted medicine cabinet practicality—stepless color temp, defogging, and having outlets/USB in the cabinet for daily devices (examples: reddit.com/r/BathroomRemodeling/comments/1l8yocd, reddit.com/r/HelpMeFind/comments/1cajfg1).

Before you order: measuring and code checklist

A few quick checks can save rework:

• Measure finished‑to‑finished shower opening and choose the pivot width range (Urban) or confirm 56–60 in for sliding (Golden). Verify plumb/level; the CALYZ frames allow about 4 in of adjustability for width.
• Confirm toilet discharge route, vertical rise, and total run length, then match to 500W/600W/750W capability with margin.
• Validate venting and electrical access for the macerator and the lighted cabinet per local code; the cabinet uses a UL‑listed plug.
• If recess‑mounting the cabinet, confirm stud spacing and recess depth; surface mounting remains an option if hidden utilities conflict.
