Integrating an under-sink Reverse Osmosis (RO) water purifier is the modern standard for luxury kitchens across Lekki, Ikoyi, Victoria Island, and Ikeja. Designed to fit neatly inside standard kitchen cabinetry, iClear under-sink purifiers deliver pure drinking water without cluttering your premium countertops. Certified iClear technicians handle the entire installation in under 90 minutes—connecting directly to your cold water line, mounting a sleek dedicated faucet, and leaving full storage space for your everyday kitchen essentials.

#### **Sleek Aesthetics Meets Modern Lagos Kitchen Design**

Modern kitchen architecture in Lagos focuses on clean lines, stone countertops, and minimalist design. Traditional plastic water dispensers, heavy sachet bags, and bulky 19-liter water bottles disrupt this aesthetic, taking up valuable floor space and introducing unsanitary storage hassles.

An under-sink RO purifier solves these problems by hiding the filtration system completely out of sight inside your lower cabinet:

- **Countertop Clarity:** Only a single, premium stainless-steel or chrome faucet is visible above your sink line.
- **Zero Dispenser Hassle:** Eliminates weekly bottled water deliveries, heavy lifting, and unappealing plastic containers.
- **Space-Efficient Dimensions:** Requiring approximately **40cm (H) x 20cm (W) x 40cm (D)**, the compact iClear unit leaves over 70% of your under-sink storage cabinet available for cleaning supplies and storage baskets.

#### **Step-by-Step Under-Sink Installation Walkthrough**

Homeowners and interior remodelers across high-end Lagos estates often wonder if installing an RO unit requires heavy masonry or plumbing overhaul. The process is non-invasive, straightforward, and completely handled by certified iClear technicians.

**1. Water Supply Connection (Feed Water Valve)**

Technicians attach a specialized cold-water T-valve adaptor directly to your existing angle stop valve underneath the sink. There is no destructive pipe cutting or structural alteration involved.

**2. Dedicated Faucet Mounting**

A precise hole is drilled into your kitchen sink deck or quartz/granite countertop to mount a sleek chrome or brushed-nickel dispensing faucet. If your sink already features a pre-drilled soap dispenser hole, it can be repurposed instantly.

**3. Drain Saddle & Pressurized Tank Setup**

The system's rejected brine water line is connected to your sink's drain pipe using a silent drain saddle clamp. The compact pressurized storage tank (5L–7L capacity) is placed alongside the multi-stage filter housing.

**4. Fridge & Ice-Maker Integration (Optional)**

For modern kitchens equipped with smart side-by-side refrigerators, iClear technicians can split the output line to supply purified, ice-clear water directly to your fridge's internal dispenser and automatic ice maker.
