MTI Whirlpoolnow offers a teak shower tray. The company pointed to the emerging style trend of adding wood accents to the bath. The handcrafted trays of Burmese teak fit all MTI shower bases and are available as a special order. The teak wood naturally wards off fungi, mold and mildew. The slats are spaced 1/8 inch apart to ensure a comfortable, safe surface.
