== Design and location == [[File:MRT BL31 Traditional station sign.svg|thumb|Sanam Chai Station Traditional sign]] Sanam Chai station is in the middle of [[Rattanakosin Island]], or Bangkok's old town zone, which is a conservation area and has historical significance. It can be considered as the only station in the inner Rattanakosin Island (around [[Royal Grand Palace]]), and regarded as one of only four MRT stations that are recognized for their most beautiful design (consisted of [[Itsaraphap MRT Station|Itsaraphap station]], Sanam Chai station, [[Sam Yot MRT Station|Sam Yot station]], and [[Wat Mangkon MRT Station|Wat Mangkon station]]).
The interior is finished under the theme of the early [[Rattanakosin era]], as designed by expert in [[Thai architecture]] and national artist [[Pinyo Suwankiri]]. The inside is decorated with Sadom pillars (main pillar), these are etched with tiles carve into the shape of the [[Mimusops elengi|Pikul]] flower sharpe, which signify prosperity, with the pillar edges adorn with blooming lotus shapes, with long curve petals leaning toward the centre, the bottom of each large petals engrave with smaller petals and coated in [[gold leaf]]. The floor and walls made of resemble the city walls. The ceiling painted with star sharpe stencils to resemble the atmosphere of the throne hall in Rattanakosin era. The station has a higher ceiling than most MRT stations along the line as the ventilation system was installed to the side of the station instead of directly above it.
Entry-exit 1 has been specifically designed by CH.Karnchang, PLC. without a roof and with specially designed escalators, in order to not obscure the view of Museum Siam located behind the exit.<ref>{{Cite web|url=http://27.254.189.213//Upload/web_file_manager_91253_1564127111_40108_file1.pdf|title=BEM Magazine ฉบับพิเศษ เปิดให้บริการโครงการรถไฟฟ้าสายสีน้ำเงินส่วนต่อขยาย|last=|first=|date=|website=|archive-url=https://web.archive.org/web/20190817075341/http://27.254.189.213//Upload/web_file_manager_91253_1564127111_40108_file1.pdf|archive-date=2019-08-17|access-date=|url-status=dead}}</ref><ref>{{Cite web|url=https://www.pf.co.th/blog/home-discovery/2018/04/27/didyouknow-sanamchai-station/|title=เรื่องน่ารู้เกี่ยวกับ "สถานีสนามไชย" สถานีรถไฟใต้ดินที่สวยที่สุดในประเทศไทย|last=|first=|date=|website=|archive-url=|archive-date=|access-date=}}</ref>
