Solido+ BOX and compatible frames WC Frame 4in1 WC Frame 3in1 WC + WC Frame 5in1 Review: Love Grohe products - I've had two of these installed now, the installer was surprised when I said how much I'd paid on desertcart too. These just seem to have an engineered quality about them, I've also bought Grohe taps and shower systems. The wall mounting of the pan is hygienic and looks better, especially in a small room, yet feels more solid than a floor mounted pan. Look for the kit that comes with everything including the flush plate, as these are the best value IMHO. The flush is powerful and always cleans the bowl first time. I coupled this with a Rimless RAK Resort Compact D Shape Wall Hung Toilet WC Soft Close Seat 520, which is well made and incredible value. Review: Great kit - Very easy to install. Works perfectly. Everything good quality. Would get again. ## Features - Including wall plate Skate Air and wall brackets for on-the-wall installation - Highly flexible - 200 mm height adjustment - Tool-free latching of inspection shaft, frame for actuation plate is mounted with two screws only, for vertical or horizontal use - 4 modes of operation: dual flush (6/3l)or or non-interruptible single flush (6l) - GROHE Whisper „Whisper-quiet“ flow noise for added comfort. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005OQ2HWO | | Best Sellers Rank | 37,337 in DIY & Tools ( See Top 100 in DIY & Tools ) 78 in Shower Hoses | | Brand | GROHE | | Connector Type | G Connector | | Country of Origin | Germany | | Customer Reviews | 4.6 out of 5 stars 367 Reviews | | Exterior Finish | Chrome | | Exterior finish | Chrome | | Global Trade Identification Number | 04005176863288 | | Included Components | GROHE 38772001 - Cosmo Rapid SL Cisterna Empotrada | | Inlet Connection Size | 24 Centimeters | | Inlet Connection Type | Flange | | Inlet connection size | 24 Centimeters | | Inlet connection type | Flange | | Item Dimensions | 111 x 52.5 x 15.5 centimetres | | Item Type Name | Wall Hung Toilet Fame with Cistern | | Item Weight | 1 Kilograms | | Item dimensions L x W x H | 111 x 52.5 x 15.5 centimetres | | Manufacturer | Grohe | | Material | Plastic, Stainless Steel | | Model Number | 38772001 | | Number of Pieces | 3 | | Number of Ports | 2 | | Outlet Connection Size | 0.5 Inches | | Outlet Connection Type | G Connector | | Part Number | 38772001 | | Set Name | 3-in-1 set | | Size | 52.5 cm (W) x 111 cm (L) x 15.5 cm (H) | | Thread Size | 24 centimeters | | Thread Type | Thread | | Valve Type | Gate Valve | ## Product Details - **Brand:** GROHE - **Exterior finish:** Chrome - **Inlet connection size:** 24 Centimeters - **Inlet connection type:** Flange - **Item dimensions L x W x H:** 111 x 52.5 x 15.5 centimetres - **Material:** Plastic, Stainless Steel - **Number of Packs:** 3 - **Number of ports:** 2 - **Outlet connection size:** 0.5 Inches - **Outlet connection type:** G Connector ## Images ![GROHE Rapid SL 3-in-1 Wall-Hung Toilet Concealed Installation System Set Frame 1.13m with Dual Flushing Cistern GD 2, 6 l - 9 l, Wall Brackets, Skate Cosmopolitan Chrome Flush Plate, 38772001 - Image 1](https://m.media-amazon.com/images/I/61L58aXOmBL.jpg) ![GROHE Rapid SL 3-in-1 Wall-Hung Toilet Concealed Installation System Set Frame 1.13m with Dual Flushing Cistern GD 2, 6 l - 9 l, Wall Brackets, Skate Cosmopolitan Chrome Flush Plate, 38772001 - Image 2](https://m.media-amazon.com/images/I/61m4zCptm0L.jpg) ![GROHE Rapid SL 3-in-1 Wall-Hung Toilet Concealed Installation System Set Frame 1.13m with Dual Flushing Cistern GD 2, 6 l - 9 l, Wall Brackets, Skate Cosmopolitan Chrome Flush Plate, 38772001 - Image 3](https://m.media-amazon.com/images/I/21zKi07QOqL.jpg) ![GROHE Rapid SL 3-in-1 Wall-Hung Toilet Concealed Installation System Set Frame 1.13m with Dual Flushing Cistern GD 2, 6 l - 9 l, Wall Brackets, Skate Cosmopolitan Chrome Flush Plate, 38772001 - Image 4](https://m.media-amazon.com/images/I/71Q7hq8SYIL.jpg) ![GROHE Rapid SL 3-in-1 Wall-Hung Toilet Concealed Installation System Set Frame 1.13m with Dual Flushing Cistern GD 2, 6 l - 9 l, Wall Brackets, Skate Cosmopolitan Chrome Flush Plate, 38772001 - Image 5](https://m.media-amazon.com/images/I/61AHzrP8Q7L.jpg) ## Questions & Answers **Q: The cut off valve is not working and the water overflows into the pan. Is this a fault? And if so can it be fixed without uninstalling it?** A: Hi, Generally, they valve can be replaced without removing the cistern but Grohe woud potentially provide their won engineer to resolve for you. If you contact Grohe the manufacturer they will advise on what can be done as the warranty is direct with them.

Regards Plumbingforless **Q: Can the flush plate be changed? Is it a universal fitting? Thanks** A: The flush plate can be changed on this but it has to be a Grohe flush plate as it is not universal **Q: If the void where I want to install this is more than 230mm can I not use it? I have a soil pipe which is 250mm out from the wall it sits alongside.** A: You can install wall hunt toilet you just have to Build the fixings on the wall out by putting a piece of timber there and then you need a Bendy sort pipe that should work **Q: Hi, is there a way to adjust water stream speed or tank height? Thanks** A: Yes you can adjust the tank height by adjusting the frame which raises or lowers the toilet. You can adjust the volume of the water.
