Product Overview
Pentair 79206700 is large PVC pool light niche housing pool light fixture. Niche mounts in pool wall during construction providing watertight housing for underwater light. Niche costs $80-$150 accommodating large pool lights. PVC construction resists pool chemicals and provides electrical insulation.
Niche includes mounting flange, conduit connection, and light mounting provisions. Proper niche installation is critical for safe pool lighting. Improper installation creates electrical hazards and water leaks. Professional installation ensures code compliance and safety.
The pool parts and accessories collection offers pool lighting components.
Installation Timing
Niche installs during pool construction before plaster or liner installation. New pool construction is ideal time for niche installation. Niche cannot be installed in existing pool without major renovation. Retrofitting niche requires cutting pool wall and extensive repair work.
Concrete pools: Install niche during steel installation before shotcrete or gunite. Niche mounts to rebar cage. Shotcrete encases niche flange creating watertight seal. Plaster finishes around niche face.
Vinyl liner pools: Install niche during wall construction before liner installation. Niche mounts to pool wall structure. Liner cuts around niche face creating seal. Proper liner installation prevents leaks around niche.
Fiberglass pools: Niche installs at factory during pool manufacturing. Fiberglass pools cannot accommodate field-installed niches. Niche is molded into pool structure. Factory installation ensures watertight integration.
Niche Positioning Requirements
Position niche 18 inches below water surface per NEC requirements. This depth ensures light remains submerged during normal operation. Exposed light creates shock hazard. Proper depth is code requirement and safety necessity.
Position niche away from steps, ladders, and diving areas. Light location should not interfere with pool use. Minimum 4 feet from steps and ladders recommended. Safe positioning prevents accidents and provides effective lighting.
Orient niche for optimal light distribution. Niche typically faces pool center providing even illumination. Multiple niches should be positioned symmetrically. Proper orientation maximizes lighting effectiveness.
Verify niche location allows conduit routing to junction box. Conduit must route from niche to deck-mounted junction box. Junction box must be 4 feet from pool edge, 8 inches above deck, and accessible. Plan conduit routing before finalizing niche position.
Installation Process Overview
Mount niche to pool structure using provided hardware. Concrete pools: Attach niche to rebar cage using wire ties. Vinyl pools: Bolt niche to wall structure. Secure mounting prevents niche movement during construction.
Connect conduit to niche conduit hub. Use waterproof conduit connection. Seal connection preventing water entry. Proper conduit connection is critical for electrical safety. Route conduit to junction box location maintaining proper slope for drainage.
Seal niche flange to pool structure. Concrete pools: Shotcrete encases flange. Vinyl pools: Liner seals against flange. Proper sealing prevents water leaks around niche. Leaking niche creates electrical hazard.
Verify niche is level and properly oriented before final securing. Unlevel niche affects light appearance and may prevent proper light installation. Proper orientation ensures light faces desired direction. Check alignment before construction proceeds.

Electrical Considerations and Code Compliance
Pool lighting requires GFCI protection per NEC. GFCI protects against electrical shock in wet environment. All pool lights must have GFCI protection. GFCI is code requirement and critical safety feature.
Junction box must be 4 feet from pool edge minimum. Junction box must be 8 inches above deck minimum. Junction box must be accessible for service. Proper junction box location is code requirement ensuring safety.
Conduit must be continuous from niche to junction box. No splices allowed in conduit. Continuous conduit prevents water entry to electrical system. Proper conduit installation is code requirement.
Bonding wire must connect niche to pool bonding system. Bonding prevents electrical potential differences. All metal pool components must be bonded. Bonding is critical safety requirement preventing shock.
Licensed electrician should perform all electrical work. Electrical code compliance requires expertise. Improper electrical installation creates serious shock hazard. Professional electrical work ensures safety and code compliance.
