KJbath manufactures SPC, PVC, acrylic, and engineered-stone shower wall panels in Foshan, China—coordinated with shower doors, trays, and hardware from the same factory, so your project gets one spec, one QC standard, and one shipment.
“Trusted by buyers from more than 190 countries since 1999.”
For hotel and apartment projects, the true cost of ceramic tile is not the tile—it is the labor, the curing time, and the maintenance liability. Industry comparisons put installed tile cost at roughly $10–25 per sq. ft. once professional tiling is included, while panel systems install at a fraction of that labor cost. A trained two-person crew can make a standard shower watertight in under two hours with tongue-and-groove panels and MS-polymer adhesive—no mortar, no curing days, no grout to fail. For a 200-room hotel renovation, that difference compounds into weeks of saved schedule and earlier room revenue.
Different projects need different panel cores. A budget rental apartment and a five-star hotel do not share a spec sheet. KJbath produces four material systems so you can standardize on one supplier across your whole portfolio.
| Material System | Core / Structure | Typical Thickness | Waterproof | Durability & Lifespan | Best For |
|---|---|---|---|---|---|
| SPCStone Plastic Composite | Limestone powder + PVC rigid core, wear layer + decor film | 4–6 mm | 100%, non-absorbent | High hardness, scratch & warp resistant; 15–20 years | Hotels, high-traffic commercial, humid climates |
| PVCHollow-Core | Extruded PVC with smooth printed surface | 5–10 mm | 100% surface; joints sealed | Lightweight, impact-moderate; 10–15 years | Rental housing, budget projects, fast retrofits |
| AcrylicResin Base | Acrylic resin base, high-gloss or solid-color finish | 3–5 mm | Excellent; joints sealed | Repairable surface (light scratches polish out); heat-sensitive | Mid-high-end residential, showrooms |
| Engineered StoneSolid Surface | Quartz/mineral + resin, CNC cut | 6–10 mm | Water absorption <0.3–0.05% | Highest rigidity & premium feel; 20+ years | Luxury hotels, flagship projects, premium OEM lines |
Project specifiers and distributors need numbers, not adjectives. Below is the standard KJbath shower wall panel specification range; OEM dimensions and decors are available against confirmed drawings.

Dimensions are standard program ranges—OEM sizing and decors are quoted against confirmed project drawings.
Panel quality failures show up months after installation—as warping, delamination, or color drift between batches. That is why our QC is a chain of checkpoints, not a final glance.
Supporting facts buyers can verify elsewhere on this site: our hardware lines undergo 100,000-cycle lifecycle testing; our glass is processed to SGCC/CE (EN 12150) tempered standards; salt-spray and drop-test protocols are documented in our quality blog series. The same QC culture covers wall panels.
Resin, limestone powder, decor films, and aluminum trims are checked against approved specification before entering production; decor film batches are color-matched against retained master samples.
Extrusion temperature, core density, thickness tolerance (±0.5 mm), and surface lamination are reviewed at workstation level during the run—not sampled after it.
Flatness, joint fit (tongue-and-groove engagement), surface defect review, and carton drop-test logic borrowed from our glass and hardware packaging standards.
Labeling, quantity, protective film integrity, and packing logic checked against the order; third-party inspection (SGS/BV/TÜV as buyer specifies) can be coordinated before loading.
Whether you are building a retail wall-panel line or specifying a 500-room hotel, the commercial mechanics matter as much as the product. KJbath supports:
Panel economics only work if installation is genuinely simple. The KJbath system is designed around a three-step site workflow that general contractors can standardize across crews. A standard 4 m² shower enclosure is watertight in roughly 90 minutes—industry benchmarks show panel crews achieving 2–3× the daily output of tiling crews.
Wall surface clean, dry, and reasonably flat; dry-fit aluminum L-track level before any adhesive is applied.
Apply MS-polymer adhesive in a serpentine bead (or engage the click system), press panel, check plumb with laser.
Color-matched silicone at vertical joints, corners, and fixture penetrations—the enclosure is watertight in roughly 90 minutes.
Project packing: Panels ship on A-frames or flat pallets with protective film, corner guards, and room/zone labels for project orders.
Freight economics: Panels are dramatically lighter than tile per covered area—more square meters per container; panel weight can cut freight cost to roughly 1/5 of equivalent tile shipments.
One shipment: Mixed loading with shower doors and trays from the same factory—one booking, one customs entry, one QC standard.
KJbath’s project discipline was built on demanding commercial jobs—like the 150+ custom glass door sets delivered for an office building in Dar es Salaam, Tanzania, where upfront CAD review and zone packaging eliminated dimensional errors across dozens of non-standard openings. The same engineering workflow applies to wall-panel packages.
Standardized SPC panel packages per unit type, zone-labeled by floor, cutting on-site sorting to near zero.
Full-height panels installed over existing substrates, keeping floors open during daytime work—renovation case data across the industry shows double-digit schedule compression and zero re-grout warranty claims in the first 18 months.
Multi-decor SPC and PVC collections with private-label packaging, replenished on rolling container schedules.
KJbath didn’t just supply products; they controlled the most error-prone customization steps upfront. Their drawing review saved us from what could have been a dimensional nightmare.
— General Contractor, Commercial Project
In many bathroom projects, panels are evaluated too late—after the door and tray are already specified. When buyers evaluate them earlier, they gain a cleaner view of the full bathroom composition:
Eight questions from developers, distributors, contractors, and retailers—covering schedule, drawings, MOQ, private label, substrates, sealing, certifications, and service life.
For Developers & Project OwnersPanels eliminate mortar curing and multi-trade sequencing. A two-person crew can make a standard shower watertight in under two hours, and crews commonly cover 2-3x the daily area of tiling teams. On multi-room projects, that typically compresses the wet-zone schedule by weeks.
For Developers & Project OwnersYes. Send your CAD drawings or BOQ—our engineering team reviews opening dimensions and panel layouts before production and flags conflicts, the same process we used to deliver 150+ non-standard commercial door sets without dimensional failures.
For DistributorsStandard MOQ is one 20GP container, and you can mix panels with shower trays, enclosures, and hardware in the same load. Panels are far lighter than tile per covered area, so each container carries significantly more square meters.
For DistributorsYes. We support OEM decors (marble, woodgrain, matte solids), custom sizes, private-label cartons, printed manuals, and SKU barcoding. OEM decor proofs take about 7-10 days.
For Installers & ContractorsPanels bond to clean, dry, reasonably flat substrates—cement board, drywall, plywood battens, and sound existing tile are all workable. SPC rigid-core panels need flatter substrates than flexible PVC; we supply trim and sealant systems for corners and penetrations.
For Installers & ContractorsTongue-and-groove or click joints plus MS-polymer adhesive, with color-matched silicone at corners and fixtures. There are no porous grout lines—the failure point responsible for most tile shower leaks is designed out.
For RetailersDepending on series: formaldehyde-free declarations, French A+ VOC-level documentation, water-absorption test reports, and fire-class documentation on request. Third-party inspection (SGS/BV/TUV) can be arranged before loading.
For RetailersSPC panels typically deliver 15-20 years of service; PVC 10-15 years; engineered stone 20+. We recommend ordering around 5% spare panels per project and stock matching trims so future repairs never require a full re-order.
